The asymmetric unit of the title compound, Cu(C2H8N2)2(H2O)22, contains one sulfamerazinate anion in a general position and one half-cation that is located on a center of inversion. The Cu(II) cation shows a strong Jahn-Teller distortion. It is coordinated by four N atoms of two ethyl-enedi-amine 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).
标题化合物Cu(C₂H₈N₂)₂(H₂O)₂₂的不对称单元包含一个处于一般位置的磺胺嘧啶阴离子和一个位于对称中心的半阳离子。Cu(II)阳离子呈现出强烈的 Jahn-Teller 畸变。它在双锥配位中，由两个乙二胺配体的四个 N 原子在基面配位，两个 O 原子在轴向位置以长得多的距离配位。在晶体中，结构单元通过 N-H⋯N、O-H⋯N、N-H⋯O 和 O-H⋯O 氢键连接成平行于(001)的二维网络。
