Abstract
The reaction of TpReOCl(StBu) (Tp = tris(pyrazolyl)borate anion) with sodium disulfide in dimethoxyethane affords the new binuclear rhenium complex [TpReO(µ-StBu)]2(µ-S2) (I). Complex I can also be synthesized by the reaction of TpReO(StBu)2 with a suspension of manganese(II) bromide in toluene accompanied by the dealkylation of one of the ligands to form one more new complex [TpReO]2(µ-S2)(µ-S) (II) containing the bridging sulfide and disulfide ligands. The structures of two crystalline solvates of complex I with dichloromethane containing the molecules with different conformations of the Re2S2 fragment (Ia and Ib) and complex II are studied by X-ray diffraction (XRD) (CIF files ССDC nos. 2262677, 2262678, and 2267423 for Ia, Ib, and II, respectively).
期刊介绍：
Russian Journal of Coordination Chemistry is a journal that publishes reviews, original papers, and short communications on all aspects of theoretical and experimental coordination chemistry. Modern coordination chemistry is an interdisciplinary science that makes a bridge between inorganic, organic, physical, analytical, and biological chemistry.
