Abstract

In the title compound, {[Cu(II)Cu(I) (2)(C(5)H(3)N(2)O(2))(2)(CN)(2)(H(2)O)(2)]·2H(2)O}(n), the Cu(II) atom lies on an inversion centre and is octa-hedrally coordinated by two N atoms and two O atoms from opposing pyrazine-2-carboxyl-ate (2-pac) ligands and two water O atoms. The Cu(I) atom has a triangular geometry, coordinated by one N atom and one C atom from two bridging cyanide ligands, and another N atom from the 2-pac ligand. The three-dimensional structure features a succession of two-dimensional sheets containing Cu(CN) chains linked by Cu(2-pac)(2)(H(2)O)(2) groups. The coordinated and free water mol-ecules are involved in an extended three-dimensional hydrogen-bond network with the 2-pac ligands.

摘要

在标题化合物{[Cu(II)Cu(I)(2)(C₅H₃N₂O₂)₂(CN)₂(H₂O)₂]·2H₂O}ₙ中，Cu(II)原子位于一个对称中心上，由来自两个反位的吡嗪 - 2 - 羧酸根（2 - pac）配体的两个N原子、两个O原子以及两个水分子的O原子进行八面体配位。Cu(I)原子具有三角几何构型，由来自两个桥连氰化物配体的一个N原子、一个C原子以及来自2 - pac配体的另一个N原子配位。三维结构的特征是一系列二维片层，其中包含由Cu(2 - pac)₂(H₂O)₂基团连接的[Cu(CN)]ₙ链。配位水分子和游离水分子参与了与2 - pac配体形成的扩展三维氢键网络。
