title: (meso-5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-4,11-diene)nickel(II) dibromide dihydrate.
abstract: The asymmetric unit of the title compound, [Ni(C(16)H(32)N(4))]Br(2)·2H(2)O, consists of one half [Ni(C(16)H(32)N(4))](2+) cation, one Br(-) anion and one water mol-ecule of crystallization. The Ni(II) ion lies on an inversion centre in a square-planar environment formed by the four macrocyclic ligand N atoms. In the crystal structure, the cations, anions and water mol-ecules are linked via inter-molecular N-H⋯Br and O-H⋯Br hydrogen bonds, forming discrete chains with set-graph motif D(2)D(2) (2)(7)D(2) (1)(3)D(3) (2)(8). The water mol-ecules and Br(-) ions are linked with set-graph motif R(4) (2)(8).
