Diaquabis(ethylenediamine-κ2N,N′)copper(II) bis(sulfamerazinate)

Abstract

The asymmetric unit of the title compound, [Cu(C2H8N2)2(H2O)2](C11H11N4O2S)2, contains one sulfamerazinate anion in a general position and one half-cation that is located on a center of inversion. The CuIIcation shows a strong Jahn–Teller distortion. It is coordinated by four N atoms of two ethylenediamine ligands in the basal plane and two O atoms at much longer distances in the axial positions in a bipyramidal coordination. In the crystal, the building blocks are connected by N—H...N, O—H...N, N—H...O and O—H...O hydrogen bonding into a two-dimensional network parallel to (001).
