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 mol­ecules. The Ni atoms are in a slightly distorted square-planar coordination by the four macrocyclic N atoms, which are almost...

Descripción
Sumario: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 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.
