Bis(4-amino-3,5-di-2-pyridyl-4H-1,2,4-triazole)diaquanickel(II) bis(perchlorate).

ABSTRACT: In the mol-ecular structure of the centrosymmetric mononuclear complex [Ni(2-bpt)(2)(H(2)O)(2)](ClO(4))(2) [2-bpt = 4-amino-3,5-di-2-pyridyl-1,2,4-triazole, (C(12)H(10)N(6))], the central Ni(II) atom is six-coordinated by a pair of chelating 2-bpt ligands and two water mol-ecules. Inter-molecular O-H?N inter-actions link the monomeric units into a two-dimensional hydrogen-bonded (4,4) network, which is extended to a three-dimensional supra-molecular aggregate via ??? stacking inter-actions [centroid-centroid distances 3.809?(3) and 3.499?(3)? Å].
