Perspective
The coordination chemistry of nitrosyl in cyanoferrates. An exhibit of bioinorganic relevant reactions
José A. Olabe,
Dalton Trans., 2008, 3633
DOI: 10.1039/b803153c
Pentacyanoferrates(II) and (III) are valuable precursors for bound nitrosyl complexes (NO+, NO, NO-). Basic structural features and bioinorganic relevant reactivity is described for the formation and dissociation reactions, nucleophilic and electrophilic additions, dinitrosyl formation and disproportionation reactions, among others.

Synthesis, structure and isomerization of arylphosphoranes with anti-apicophilic bonding modes using a novel bidentate ligand with two C2F5 groups
Xin-Dong Jiang, Shiro Matsukawa and Yohsuke Yamamoto,
Dalton Trans., 2008, 3678
DOI: 10.1039/b802947d
Arylphosphoranes with anti-apicophilic bonding modes (O-equatorial) were isolated using a novel bulky bidentate ligand with two C2F5 groups. Kinetic measurements of the isomerization (O-equatorial to O-apical) suggested that the O-equatorial isomers were stabilized by the 
*P–O interaction in the ground state.
