title: Diaquabis[2'-(4,5-diazafluoren-9-ylidene)picolinohydrazidato-kappa2N,O]zinc(II) tetrahydrate: a metal-water chain complex containing cyclic water hexamers.
abstract: In the title compound, [Zn(C17H10N5O)2(H2O)2].4H2O, cyclic water hexamers forming one-dimensional metal-water chains are observed. The water clusters are trapped by the co-operative association of coordination interactions and hydrogen bonds. The ZnII ion resides on a centre of symmetry and is in an octahedral coordination environment comprising two O atoms and two N atoms from two 2'-(4,5-diazafluoren-9-ylidene)picolinohydrazidate ligands and two water molecules.
