Abstract
The crystal structure of bis-(L-threonine) copper (II).H2O, Cu (C4H8NO3)2.H2O has been determined by heavy atom and Fourier methods and refined by least-squares using visually estimated three-dimensional x-ray data of 893 reflections. The blue crystals are monoclinic, space groupP21 withα=11·02,b=4·90,c=11·16Å andβ=93·5°,Z=2. The finalR is 0·10. Coordination of copper is distorted square pyramidal with ligands intrans configuration. The conformation of one of the aminoacid ligand is identical with Ls-Threonine while the other has a conformation with torsional angleχ 1, 2=−74(1)°.
