Tris(2-sulfidopyridine N-oxide-O,S)chromium(III) Acetone Solvate (1/1)

The title compound, [Cr(C₅H₄NOS)₃].(CH₃)₂CO, contains a Cr(III)(mpo)₃ unit (Hmpo = 2-mercaptopyridine-N-oxide) and (CH₃)₂CO. Each mpo^- ligand chelates to the Cr atom via one O and one S atom with an average bite angle of 83.3 (1)°, forming a distorted octahedral O₃S₃ coordination around the Cr atom. The average Cr-S and Cr-O bond distances are 2.363 (1) and 1.986 (2) Å, respectively.
