Abstract

Three new Ni(II) coordination compounds with anions of 4,8-disulfo-2,6-naphthalenedicarboxylic acid (H4dsndc) and 1,2-bis(4-pyridyl)ethylene (bpe), differing in dimensionality and structure, were obtained: the molecular complex [{Ni(H2O)5}2(bpe)](dsndc), the one-dimensional coordination polymer [Ni(H2O)4(bpe)](H2dsndc)·2H2O, and the two-dimensional coordination polymer [{Ni(H2O)3}2(bpe)2(dsndc)]·2H2O. The structures of the compounds were determined by single-crystal X-ray diffraction analysis. The compound [Ni(H2O)4(bpe)](H2dsndc)·2H2O was obtained in chemically and phase-pure form and characterized by a standard set of physicochemical methods (powder X-ray diffraction, elemental and thermogravimetric analyses, and IR spectroscopy).
