Crystal structure of catena-(hexaaqua-1κ6O)(chloro-2κCl)bis(μ- pyridine-2,5-dicarboxylato-1κO:2κ2N,O')gadolinium(III)zinc(II), GdZn(H2O)6(C7H3NO4)2Cl

Abstract

Source of materialAm ixture of pyridine-2,5-dicarboxylic acid (2.0 mmol, 0.3342 g), gadolinium oxide (1.0 mmol, 0.3625 g), zinc chloride (1.0 mmol, 0,1363 g), KOH (2.0 mmol, 0.102 g), and H 2 O (10 mL) was placed in aTeflon-lined autoclave heated to 433 K for three days. The autoclave was then allowed to cool to room temperature. Colorlessc rystalsw ere collected by filtration and washed repeatedly with distilled water and diethyl ether.
