Penta-aqua-(4,6-dihy-droxy-benzene-1,3-disulfonato-κO(1))zinc penta-hydrate
Abstract:
The Zn(II) atom in the title complex, [Zn(C(6)H(4)O(8)S(2))(H(2)O)(5)]·5H(2)O, is coordinated by five water mol-ecules and an O atom of a 4,6-dihy-droxy-benzene-1,3-disulfonate dianion. The coord-ination geometry is distorted octa-hedral, with the Zn-O(sulfonate) bond relatively long compared to the Zn-O(water) bonds. The coordinated and lattice water mol-ecules inter-act with each other and with the hy-droxy groups and sulfonate ligand through O-H⋯O hydrogen bonds, generating a tightly held three-dimensional network.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
