(meso-5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetra­aza­cyclo­tetra­deca-4,11-diene)nickel(II) dibromide dihydrate

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 mol­ecule 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 mol­ecules are linked via inter­molecular 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 mol­ecules and Br(−) ions are linked with set-graph motif R (4) (2)(8).
