Tris(ethyl-enediamine)-nickel(II) 1H-pyrazole-3,5-dicarboxyl-ate 1.67-hydrate.

ABSTRACT: The asymmetric unit of the title compound, [Ni(C(2)H(8)N(2))(3)](C(5)H(2)N(2)O(4))·1.67H(2)O, consists of three [Ni(en)(3)](2+) dications (en is ethyl-enediamine), three [(pzdc)(3)](2-) dianions (pzdc is pyrazole-3,5-dicarboxyl-ate) and five water mol-ecules. In each complex dication, the Ni(II) atom is coordinated by six N atoms from three en ligands forming a distorted octa-hedral coordination geometry. In the crystal, the ions and water mol-ecules are linked into a three-dimensional framework by a large number of N-H?O and O-H?O hydrogen bonds.
