Dalton Transactions

1.0 Scope and standards 

Dalton Transactions  embraces all aspects of the chemistry of inorganic and organometallic compounds, including biological inorganic chemistry and solid-state inorganic chemistry (in particular work which explores the synthesis and analysis of materials); the application of physicochemical and computational techniques to the study of their structures, properties and reactions, including kinetics and mechanisms; new or improved experimental techniques and syntheses. Manuscripts which describe purely physical, crystallographic or computational work must include the clear relevance of the work to the broad inorganic and organometallic readership of Dalton Transactions.

All contributions are judged on the criteria of (i) originality and quality of scientific content and (ii) appropriateness of the length to content of new science. Thus, papers reporting results which would be routinely predicted or result from application of standard procedures or techniques are unlikely to prove acceptable in the absence of other attributes which themselves make publication desirable. 

Acceptance of a contribution for Chemical Communications or as a Dalton Transactions Communication does not guarantee that the corresponding full paper will be accepted for Dalton Transactions; although publication of a full account is strongly encouraged, its acceptability will depend on whether or not it contains significant new details, new interpretations or new results. 


2.0 Article types 

2.1 Communications 
Preliminary accounts of original and significant work of such importance that rapid publication is justified may be published in Communication form. Material intended for Dalton Transactions Communications should be of specific specialist interest to inorganic chemists. Full papers based upon Communications will be acceptable provided that they represent a substantial amplification and extension of the original material. The recommended length for a communication is three printed journal pages, however some flexibility is allowed. 

2.2 Full Papers 
Full papers contain original scientific work that has not been published previously. However, work that has appeared in print in a short form such as a Dalton Transactions Communication or Chemical Communication is normally acceptable. 

2.3 Perspectives
Dalton Transactions
Perspectives are short readable articles covering current areas of interest for an inorganic chemistry audience. They may take the form of personal accounts of research or a critical analysis of activity in a specialist area. By their nature they will not be comprehensive reviews of a field of chemistry. Since the readership of Dalton Transactions is wide-ranging the article should be easily comprehensible to a non-specialist in the field, whilst at the same time providing an authoritative discussion of the area concerned.

2.4 Frontiers 
Dalton Transactions Frontiers are normally published by invitation of the Editorial Board. However, suggestions from authors are welcome and enquiries regarding the submission of Dalton Transactions Frontiers should be directed to the Editor. Frontiers in Dalton Transactions are short articles that highlight recent important new developments in all areas inorganic and organometallic chemistry, including biological inorganic chemistry and solid-state inorganic chemistry. The article should explain the significance of these developments and may also identify where further work is urgently required or where challenges are still faced. Please note that no new work should be presented. The article can be a short, personal account of a new area of research and can be speculative in nature, putting a new area in perspective. Frontiers should be around 2-3 journal pages, although this may vary slightly depending on the nature of the article. 

2.5 Letters 
Letters are a medium for the expression/exchange of scientific opinions/views normally concerning material published in Dalton Transactions, but not for revision/updating of authors' own work. They are not intended to compete with media for the publication of more general matters, such as Chemistry World. Only rarely should a Letter exceed one printed column in length (about 1-2 pages of typescript). Where a Letter is polemical in nature, and if it is accepted, a Reply will be solicited from other parties implicated for publication alongside the original Letter.


3.0 Characterisation guidelines

3.1 Characterisation of new compounds
It is the responsibility of authors to provide fully convincing evidence for the homogeneity, purity and identity of all compounds they claim as new. This evidence is required to establish that the properties and constants reported are those of the compound with the new structure claimed. Referees will assess, as a whole, the evidence presented in support of the claims made by the authors. The requirements for characterisation criteria are detailed below.

 3.2 Inorganic and Organometallic compounds
A new chemical substance (molecule or extended solid) should have a homogeneous composition and structure. Where the compound is molecular, authors must provide data to unequivocally establish its homogeneity, purity and identification. In general, this should include elemental analyses that agree to within A±0.4% of the calculated values. In cases where elemental analyses cannot be obtained (e.g. for thermally unstable compounds), justification for the omission of this data should be provided. Note that an X-ray crystal structure is not sufficient for the characterisation of a new material, since the crystal used in this analysis does not necessarily represent the bulk sample. In rare cases, it may be possible to substitute elemental analyses with high-resolution mass spectrometric molecular weights. This is appropriate, for example, with trivial derivatives of thoroughly characterised substances or routine synthetic intermediates. In all cases, relevant spectroscopic data (NMR, IR, UV-vis, etc.) should be provided in tabulated form or as reproduced spectra. These may be relegated to the Supplementary Information to conserve journal space. However, it should be noted that, in general, mass spectrometric and spectroscopic data do not constitute proof of purity, and, in the absence of elemental analyses, additional evidence of purity should be provided (melting points, PXRD data, etc.). 
Where the compound is an extended solid, it is important to unequivocally establish the chemical structure and bulk composition. Single crystal diffraction does not determine the bulk structure. Referees will normally look to see evidence of bulk homogeneity. A fully indexed powder diffraction pattern which agrees with single crystal data may be used as evidence of a bulk homogeneous structure and chemical analysis may be used to establish purity and homogeneous composition.
