In the title compound, {[Cu(C(6)H(2)N(2)O(4))(C(3)H(7)NO)]·H(2)O}(n), the Cu(II) atom is coordinated by an N,O-bidentate pyrazine-2,3-dicarboxyl-ate (pzdc) dianion, two O atoms from two other pzdc anions and one O atom from the dimethlyformamide ligand, forming a distorted square-pyramidal CuNO(4) geometry. The polymeric character of the structure is established by the formation of layers parallel to (100) via bridging pzdc ligands. O-H⋯O hydrogen bonding between water mol-ecules and uncoordinated carboxyl-ate O atoms leads to additional stabilization of the structure.
在标题化合物{[Cu(C₆H₂N₂O₄)(C₃H₇NO)]·H₂O}ₙ中，Cu(II)原子由一个N,O-双齿的吡嗪-2,3-二羧酸根（pzdc）二价阴离子、来自另外两个pzdc阴离子的两个O原子以及来自二甲基甲酰胺配体的一个O原子配位，形成一个扭曲的四方锥CuNO₄几何构型。该结构的聚合特性通过桥连pzdc配体形成平行于(100)的层得以确立。水分子与未配位的羧酸根O原子之间的O—H⋯O氢键导致结构进一步稳定。
