The Crystal and Molecular Structure of catena-{Aquabis[2-methyl-2-(phenylthio)-propanoato]cadmium(II) monohydrate}

Abstract

The crystal structure of the cadmium complex of 2-methyl-2-(phenylthio) propanoic acid, [ Cd (C₆H₅SC(CH₃)₂CO₂)₂(H₂O)]. H₂O has been determined by X-ray diffration and refined to a residual R 0.051 for 2725 observed reflections. Crystals are orthorhombic, space group Pbca with a 10.819(2), b 9.030(1), c 47.24(2) A and Z 8. The stereochemistry about cadmium is distorted MO₆S seven-coordinate with Cd -S 2.747(2)Ǻ and a Cd -O range 2.277-2.491(5)Ǻ. Bonds are from cadmium to a water, and to four oxygens from two bidentate carboxylate groups, one of which also forms a polymer link. The same carboxylate group is also involved in a five- membered (S,O) chelate ring.
