Group 15 Metal Complexes With Carboxylic Acids. Preparation and Crystal Structure of Polymeric Ammonium Aquabis[(+)-tartrato(2-)]bismuthate(III) Hydrate
The crystal structure of the bismuth(III) complex with (+)-tartaric acid, ammonium aquabis [(+)-tartrato (2-)] bismuthate (III) hydrate, has been determined by X-ray methods and refined to a residual R 0.020 for 1288 observed reflections. Crystals are orthorhombic, space group P 212121 with Z 4 in a cell of dimensions a 7.4712(4), b 10.856(1), c 17.609(3) � . Each nine-coordinate MO9 bismuth centre comprises three bidentate α-hydroxy carboxy residues from two tartrato (2-) ligands (with one bridging), an asymmetric bidentate carboxylato (O,O') group, and a water. The Bi-O range is 2.372(7)-2.738(6) � [mean 2.509(6) >� ]. The resultant structure is a linear polymer which is stabilized by extensive hydrogen-bonding interactions.
