Crystal structure and magnetic interactions in bis(D,L-alaninato)copper(II) hydrate

Abstract: The title compound, Cu(NH 2 CHCH 3 CO 2 ) 2 •H 2 O [Cu(D,L-ala) 2 •H 2 O], crystallizes in the space group C2/c, with a=12.087 (3) A, b=9.583 (3) A, c=8.973 (3) A, β=110.85 (2)°, and Z=4. The structure was solved from 737 X-ray reflections and refined to R=0.032. The Cu(II) ion is at an inversion center, bound to the amino nitrogen and to one of the carboxylate oxygens of two symmetry-related (D and L) alanine molecules. Two water oxygens complete an elongated octahedral arrangement of ligands around the copper ions
