title: The triclinic polymorph of dibromo[(-)-sparteine-kappa2N,N']zinc(II).
abstract: The title compound, [ZnBr(2)(C(15)H(26)N(2))], when synthesized starting from Zn(0), is obtained in two polymorphic forms, one belonging to space group P2(1)2(1)2(1) and one to P1. The present contribution deals with the triclinic phase, which is isostructural with the orthorhombic form but presents a larger metal-metal intermolecular separation; the Zn.Zn distance is 7.4715 (6) A for the triclinic polymorph as opposed to 6.534 A for the orthorhombic polymorph.
