Crystal structure of (ethylenediammonium-N,N '-di-3-propanoic acid) tetrachloropalladate(II) complex

Abstract

The title compound was obtained by a synthesis from ethylenediamine-N,N'-di-3-propanoic acid dihydrochloride (H(2)eddp . 2HCl) and potassium hexachloropalladate(IV) ( molar ratio 1: 1, in water). Its structure has been determined by single-crystal X-ray diffraction: monoclinic space group P2(1)/n, a = 8.198(1), b = 10.282(1), c = 9.080(1) Angstrom, beta = 103.62(1) degrees, V = 743.9(2) Angstrom(3), and Z = 2. The dianionic complex has a square-planar coordination geometry with four chloro ligands, and ethylenediamine-N,N'-di-3-propanoic acid as dication in the second coordination sphere. This is the first reported Pd(II) structure with uncoordinated H(2)eddp.
