The reaction of Ph2BiCl with (PhS)Li or (2,6-Me 2C6H3S)Li yielded [Ph2BiSPh] ∞ (7) or Ph2BiS(2,6-Me2C 6H3)] (8), respectively. Both compounds have been characterized by elemental analysis, melting point, FT-IR, FT-Raman, solution 1H and 13C{1H} NMR, and X-ray crystallography. The solid-state structure of 7 is polymeric via long intermolecular Bi...S interactions and μ-SPh groups, yielding a distorted ψ-trigonal bipyramidal C2S2 bonding environment for bismuth. Increasing steric bulk at the phenyl thiolate ligand in 8 results in the isolation of a monomeric species, which exhibits a distorted ψ-tetrahedral C2S bonding environment for bismuth. Comparison to previously reported structures of diorganobismuth chalcogenolates shows the effect of altering the chalcogen on intermolecular Bi...E (E = O, S, Se) bond formation. DFT calculations are employed to rationalize the bonding environments at bismuth and the observed polymeric structures. This work represents the first examples of structurally characterized R2BiSR′ species and advances our understanding of intermolecular bonding in bismuth chalcogenolates.
