Abstract
In the title compound, [Zn(4)(C(16)H(10)N(4)O(2))(4)]·4H(2)O, the N'-[(8-oxidoquinolin-7-yl)methyl-idene]isonicotinohydrazidate (L(2-)) ligand binds to the metal ions, forming stable five- and six-membered chelate rings, leaving the pyridyl groups free. The compound is a tetra-nuclear Zn(II) complex centered about a fourfold roto-inversion axis, with the ligand coordinating in the doubly deprotonated form. The Zn(II) atom has a distorted square-pyramidal geometry being coordinated by one N and two O-atom donors from the doubly deprotonated L(2-) ligand, and by one N atom and one O-atom donor from a symmetry-related L(2-) ligand. In the crystal, four symmetry-related lattice water mol-ecules, centred about a fourfold roto-inversion axis, form a cyclic tetra-mer through O-H⋯O hydrogen bonds. These tetra-mers connect to the complex mol-ecules through O-H⋯N hydrogen bonds, forming a chain propagating along [100]. Neighbouring mol-ecules are linked by π-π inter-actions [centroid-centroid distance = 3.660 (2) Å] involving the quinolidine rings.
