“…The synthesis of the Co 2 (NO) 4 (SR) 2 derivatives has been carried out in a mixture of methanol and tetrahydrofuran (THF). 7 However, the exact amount of the used THF has not been specified in the original publication. Therefore, a volume fraction of 0.5 was assumed.…”

“…6 More recently, Bitterwolf and Pal prepared cobalt analogues of the Roussin's red salt esters (open structure (O), Scheme 1) by the reaction at room temperature of LiSR or LiSeR compounds with the readily prepared Co 2 (NO) 4 (m-Cl) 2 . 7 The resulting cobalt nitrosyl thiol and selenol derivatives are relatively air sensitive and tend to decompose over time, even at À78 1C. Beside the characteristic bands of the Co 2 (NO) 4 (m-SR) 2 compounds, additional bands attributed to the isonitrosyl linkage isomer, Co(NO) 3 (ON)-(m-S-t Bu) 2 , were also observed ( t Bu = C 4 H 9 ).…”

“…the cis and trans stereoisomers). 7 A theoretical study of these compounds is presented in this paper. Just like the related Co 2 (CO) 6 (SR) 2 derivatives, 8 not only the open structure (O), with four Co-S bonds but no direct Co-Co or S-S bond, should be expected, but also its butterfly (B) isomer in which the central unit is formed by a direct Co-Co bond bridged by a SR group and a NO ligand, while the remaining SR group is displaced into a terminal position (Scheme 1).…”

Density functional theory calculations on the Co(2)(NO)(4)(SR)(2) compounds (R = CH(3), CF(3) and C(4)H(9)) predict butterfly and open isomeric structures with and without a direct Co-Co bond. The open Co(2)(NO)(4)(SR)(2) structures are favored over the butterfly isomers, in terms of relative energy. Furthermore the open structures are predicted to have approximately twice as large HOMO-LUMO gaps than the butterfly Co(2)(NO)(4)(SR)(2) isomers. For the related Co(2)(CO)(6)(SR)(2) species, competing open and butterfly structures with similar HOMO-LUMO gaps were predicted. This could explain why the Co(2)(NO)(4)(μ-SR)(2) compounds have already been synthesized and why no genuine Co(2)(CO)(6)(SR)(2) derivatives have yet been reported.

The coordination chemistry of metal nitrosyls has expanded rapidly in the past decades due to major advances of nitric oxide and its metal compounds in biology. This review article highlights advances made in the area of multinuclear metal nitrosyl complexes, including Roussin’s salts and their ester derivatives from 2003 to present. The review article focuses on isolated multinuclear metal nitrosyl complexes and is organized into different sections by the number of metal centers and bridging ligands.

The present article reviews structures, properties, reactivity and applications of transition metal complexes supported by the parent thiophenolate ligand system and various derivatives thereof. This extensive outline of literature published in the last decade covers publications about di‐ and higher nuclear complexes that exhibit bridging thiophenolate functions. The structuring of this contribution is based on the type of ligand involved in the coordination, covering monodentate thiophenolate ligands as well as bi‐ and higher dentate derivatives being acyclic or macrocyclic. An emphasis is set on structures but reactions, reactivity and catalysis, redox chemistry, and other properties of the complexes in review are discussed where appropriate.
