Heavy-Metal π Complexes. 13. Trichloro(1,2,3-trimethylbenzene)bismuth(III)

The title compound, [BiCl₃(1,2,3-Me₃C₆H₃)], contains quasi-dimeric units of arene-coordinated BiCl₃ fragments that are further associated via additional Bi—Cl contacts to form coordination-polymeric layers. The resulting coordination number of Bi is 3 + 3 + 1 (primary + secondary Cl contacts + arene). The Bi—arene bonding is characterized by Bi—C distances in the range 3.168 (7)–3.751 (8) Å.
