Dipotassium tetra-aqua-bis-(?-citrato-?(4) O:O',O'',O''')nickelate(II) tetra-hydrate.

ABSTRACT: The title complex, K2[Ni2(C6H5O7)2(H2O)4]·4H2O, is a dinuclear centrosymmetric anionic octa-hedral complex, involv-ing citrates as tridentate and bridging ligands, and coordinating water mol-ecules. An extensive network of hydrogen bonds connects the complex anions through the two unique uncoordinating water mol-ecules. The K(+) counter cation is surrounded by seven O atoms in the form of an irregular polyhedron and further stabilizes the crystal packing.

In the anion, the carboxyl-ate group is twisted from the attached benzene ring at 8.84?(17)°. In the crystal, a three-dimensional hydrogen-bonding network, formed by classical O-H?O and N-H?O hydrogen bonds, consolidates the crystal packing, which exhibits ?-? inter-actions between the benzene and pyridine rings, with centroid-centroid distances of 3.458?(1) and 3.606?(1)?Å, respectively.

Tetra-aqua-bis[(1-ammonio-1-phosphono-ethyl)phospho-nato]zinc(II) tetra-hydrate.

Project description:The title compound, [Zn(C(2)H(8)NO(6)P(2))(2)(H(2)O)(4)]·4H(2)O, was synthesized by the reaction of ZnCl(2) with 1-amino-ethane-1,1-diyldiphospho-nic acid in aqueous solution. The asymmetric unit contains one-half of the complex and two water mol-ecules of solvation. The Zn atom occupies a special position on an inversion centre.

The crystal structure displays N-H⋯O and O-H⋯O hydrogen bonding, which creates a three-dimensional network.
