Dalton Trans., 2008, 2680
DOI: 10.1039/b719223a

Copper(II) 12-metallacrown-4 complexes of 
-, - and 
-aminohydroxamic acids: a comparative thermodynamic study in aqueous solution
Matteo Tegoni, Maurizio Remelli, Dimitri Bacco, Luciano Marchiò and Francesco Dallavalle,
Dalton Trans., 2008, 2693
DOI: 10.1039/b718765c
The solution stability of the CuII 12-metallacrown-4 with -aminohydroxamates is mainly entropy-driven. For -aminohydroxamates 
G° is enthalpy-driven, while for -amino derivatives both effects are operating.
Effect of metal dilution on the light-induced spin transition in [FexZn1-x(phen)2(NCS)2] (phen = 1,10-phenanthroline)
Chérif Baldé, Cédric Desplanches, Alain Wattiaux, Philippe Guionneau, Philipp Gütlich and Jean-François Létard,
Dalton Trans., 2008, 2702
DOI: 10.1039/b800248g
The thermal and light-induced spin transitions in [FexZn1-x(phen)2(NCS)2] (phen = 1,10-phenanthroline) have been investigated by magnetic susceptibility, photomagnetism and diffuse reflectivity measurements. Evolution of thermal spin transition and of photoinduced high spin state with varying dilution x is discussed.

Ashley B. S. Curtiss, Manindranath Bera, Ghezai T. Musie and Douglas R. Powell,
Dalton Trans., 2008, 2717
DOI: 10.1039/b719646f
Two novel zinc complexes, [Zn(H2O)6][Zn(H2ccdp)(H2O)2]2·12H2O ( 1) and Na6[Zn6(ccdp)3(µ6-SO4)](OH)·10.5H2O ( 2), are reported. In 1, the zinc ion is asymmetrically coordinated to only one tetradentate part of the new dinucleating ligand. Structure of complex 2, however, has six zinc ions stabilized by the central {ZnII6(µ6-SO4)}core.

The association of the cobalt hexamine cation [Co(NH3)6]3+ to an anionic nitrate species [M(NO3)4]x- (M = Fe, Mn, Cu, Zn) leads to the formation of heteronuclear Werner-type complexes [Co(NH3)6]x[M(NO3)4]3 displaying energetic material properties suitable for various applications. The new materials can for example serve as gas generators for airbag devices.
