Crystal and molecular structure of bis(aminomethanesulphonato)copper(II)

Abstract

Crystals of the title compound are monoclinic, a= 7·064, b= 7·668, c= 7·256 all ± 0·003 Å;, γ= 88·81 ± 0·005 °, space group P2₁/n, Z= 2. The structure was determined from diffractometer data (555 independent reflections) by three-dimensional X-ray methods and refined by least squares to R 0·053. The crystals are formed from trans-bis(aminomethanesulphonato)copper(II) chelates at centres of symmetry, linked into, a three-dimensional array by hydrogen bonds and the long copper–sulphonate-oxygen contacts which give copper a distorted octahedral co-ordination-sphere (Cu–O 1·995 and 2·506. Cu–N 1·999 Å).
