Bis[tris(propane-1,3-diamine-κ(2) N,N')-nickel(II)] di-aqua-bis(propane-1,3-di-amine-κ(2) N,N')nickel(II) hexa-bromide dihydrate.

ABSTRACT: In the title compound, [Ni(C3H10N2)3]2[Ni(C3H10N2)2(H2O)2]Br6·2H2O, one Ni(2+) cation, located on an inversion centre, is coordinated by four N atoms from two ligands and by two water O atoms. The other Ni(2+) cation, located in a general position, is coordinated by six N atoms from three ligands. In both cases, the Ni(2+) cation has an octa-hedral coordination environment. The overall structural cohesion is ensured by three types of hydrogen bonds, N-H⋯Br, O-H⋯Br and O-H⋯O, which connect the two types of complex cations, the bromide counter-anions and the lattice water molecules into a three-dimensional network.
