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

The asymmetric unit of the title complex, [Ni(C₁₆H₃₂N₄)]Br₂·2H₂O, contains two [Ni(C₁₆H₃₂N₄)]²⁺ cations, four Br⁻ anions and four uncoordinated H₂O mol­ecules. The Ni atoms are in a slightly distorted square-planar coordination by the four macrocyclic N atoms, which are almost coplanar [N—N—N—N torsion angles of 2.97 (6) and 3.12 (7)°]. In the crystal, a network of N—H...Br, O—H...Br and N—H...O hydrogen bonds leads to the formation of a chain structure.
