T. Fietz et al., SYNTHESIS AND MOLECULAR-STRUCTURE OF CHLORO(3-THIAPENTANE-1,5-DITHIOLATO)OXORHENIUM(V), Inorganica Chimica Acta, 231(1-2), 1995, pp. 233-236
Reaction of [BzEt(3)N][ReOCl4] (1) with 0.9 equiv, of 3-thiapentane 1,
5-dithiol (HSSSH) in chloroform delivers [ReO(SSS)Cl] (2). The chloro
ligand can be substituted by mercaptides when 2 is heated with an exce
ss of a mercaptane, e.g. C2H5SH, in acetonitrile. Single crystal X-ray
analysis of 2 shows square-pyramidal geometry.
