چکیده
The asymmetric unit of the title complex, [Ni(C(16)H(32)N(4))]Br(2)·2H(2)O, contains two [Ni(C(16)H(32)N(4))](2+) cations, four Br(-) anions and four uncoordinated H(2)O mol-ecules. 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.
