Abstract

The reaction of the electronically unsaturated Cp*₂Cr₂B₄H₈ (1; Cp* = η⁵-C₅Me₅) cluster with CS₂ yields the saturated Cp*₂Cr₂(CH₂S₂B ₄H₆) (3) cluster in better than 90% isolated yield. Both solution spectroscopic and solid-state crystallographic data show that 3, with C₂ point symmetry, contains an intracluster bridging methanedithiolato H₂CS₂ ligand in which the S atoms of the ligand have replaced two transoid BHCr bridging hydrogens in 1, which in turn have added to the carbon atom. The three compounds 1, Cp*₂Cr₂(CO)₂B₄H₆ (2), and 3 exhibit similar cluster geometries but possess 42, 44, and 46 cluster valence electrons, respectively.
