Synthesis and Crystal Structure of Novel Tetranuclear Nickel(II) Complex with Hpahqs (Hpahqs: 7-[(3,5-Dichloro-2-pyridyl)azo]-8-hydroxyquinoline-5-sulfonate)

Abstract

A novel complex [Ni4(pahqs)4(H2O)4]·20H2O was synthesized and characterized by X-ray crystallography. Except one N atom in each azo group, all the other donor atoms in the ligand were fully used in coordination to Ni(II), and the four Ni(II) were bridged by O atoms in the hydroxyquinoline moieties.
