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

Abstract

In the title complex, [Cu(C<inf>7</inf>H<inf>4</inf>NO<inf>3</inf>S)<inf>2</inf>(C<inf>2</inf> H<inf>7</inf>NO)<inf>2</inf>], the CuII 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<inf>HEA</inf> = 1.9923 (16) and Cu-N<inf>sac</inf> = 2.1776 (16) Å].
