  A series of tetragonally distorted square pyramids of formula N2S2M(NO) (M = Fe, Co) is prepared and characterized by v(NO) IR and EPR spectroscopies, magnetism and electrochemical properties, as well as solid-state crystal structure determinations. While the v(NO) IR frequencies and the ZM-N-O angles indicate differences in the electronic environment of NO consistent with the Enemark-Feltham notation of Fe(NO)}(7) and Co(No)}(8), the reduction potentials, assigned to Fe(NO)(7) + e(-) double left right arrow Fe(NO)}(8) and Co(NO)}(8) + e(-) double left right arrow Co(NO)}(9) respectively, are very similar, and in cases identical, for most members of the series. Coupled with the potential for the M(NO) units to breathe out of and into the N2S2 core plane are unique S-M-N-O torsional arrangements and concomitant pi-bonding interactions which may account for the unusual coherence of reduction potentials within the series.
• Dinitrosyl iron adducts of (N2S2)M(NO) complexes (M=Fe, Co) as metallodithiolate ligands

  Adducts of the dinitrosyl iron unit and mono-nitrosyl bis-mercaptoethanediazacycloheptane (bme-dach) iron and cobalt are described in terms of the (bme-dach)M(NO) as metallodithiolate ligands. With M = Fe, a diamagnetic (N2S2)Fe(NO)center dot Fe(NO)(2) diiron complex, in which the (N2S2)Fe(NO) unit serves as a bidentate ligand to the Fe(NO)(2) unit is derived by use of a trinitrosyliron cation as precursor to the DNIC unit as well as a NO source to cleave the [(bme-dach)Fe](2) dimer (J. Am. Chem. Soc., 2010, 132, 14118). By a similar approach of [(bme-dach)Co](2) dimer cleavage, the Co-Fe bimetallic contains (N2S2)Co(NO) as a monodentate metallothiolate ligand to Fe(NO)(2)L, L = I-Mes, 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene. Characterization of this paramagnetic cation includes infrared and EPR spectroscopies, and X-ray diffraction analysis. The latter finds a Co center dot center dot center dot Fe distance of 3.697 angstrom in contrast to the Fe-Fe bond distance of 2.7857(8) angstrom in the homobimetallic complex. (C) 2012 Elsevier Ltd.
