Substitutional disorder in a hypervalent diorganotin(IV) dihalide

The structure of bromidochloridobis[2-(dimethyl­amino­meth­yl)phen­yl]tin(IV), [SnBr(0.65)Cl(1.35)(C(9)H(12)N)(2)], contains two 2-(Me(2)NCH(2))C(6)H(4) units bonded to a Sn atom which lies on a twofold axis. The compound exhibits substitutional disorder of the halide atoms bonded to the Sn, with 1.35 occupancy for Cl and 0.65 for Br; it is isomorphous with the corresponding dichloride. The Sn atom is hexa­coordinated with a (C,N)(2)SnX (2) (X = Cl/Br) distorted octa­hedral core as a result of the strong intra­molecular N→Sn coordination trans to the Sn—X bonds (N1—Sn1—X1 = 165.8°). As a result of the inter­molecular contacts, viz. H⋯X and H⋯benzene inter­actions, the mol­ecules are arranged in a three-dimensional supra­molecular manner in the crystal structure.
