Trans-Bis(ethanolamine-N,O)bis(saccharinato-N)copper(II).

Abstract

In the title complex, [Cu(C(7)H(4)NO(3)S)(2)(C(2)H(7)NO)(2)], the Cu(II) centre lies on an inversion centre and exhibits octahedral coordination, with the two ethanolamine (Hea) and two saccharinate [sac; anionic 1,2-benzisothiazol-3(2H)-one 1,1-dioxide] ligands in a trans configuration. The bidentate Hea ligands bridge axial and equatorial positions and the sac anions occupy equatorial sites around the distorted octahedral copper(II) centre [Cu--O = 2.3263 (16), Cu--N(Hea) = 1.9923 (16) and Cu--N(sac) = 2.1776 (16) A].
