Tris[bis­(2-methyl­prop­yl)dithio­phosphinato]bis­muth(III)

The title compound, [Bi(C₈H₁₈PS₂)₃], contains a Bi^III cation surrounded by three bis­(2-methyl­prop­yl)dithio­phosphinate anions, leading to a distorted octa­hedral coordination for the heavy metal. The Bi—S and S—P bond lengths are in the ranges 2.7694 (18)–2.8391 (17) and 2.019 (2)–2.035 (2) Å, respectively. The crystal structure is consolidated by C—H...S hydrogen bonds. Intra­molecular C—H...π inter­actions also play a role in stabilizing the mol­ecules.
