The asymmetric unit of the title compound, Cu(C(13)H(20)N(2)O(2))(2)(2), contains one half-dication, located on an inversion center, and one thio-cyanate anion. Each Cu(II) atom is four-coordinated by two phenolate O and two imine N atoms from two symmetry-related Schiff base 2-{[2-(isopropyl-aza-nium-yl)eth-yl]imino-meth-yl}-6-meth-oxy-phenolate (L) ligands in a distorted square-planar geometry. The ammonium groups are involved in the formation of N-H⋯O and N-H⋯N hydrogen bonds, which link one dication and two anions into an electroneutral cluster. When very weak Cu-N interactions with a distance of 2.910 (5) Å between the metal and the thiocyanate anions in apical positions are considered, the secondary coordination polyhedron is a very elongated CuN(4)O(2) octahedron.
标题化合物Cu(C₁₃H₂₀N₂O₂)₂₂的不对称单元包含一个位于对称中心的半二价阳离子和一个硫氰酸根阴离子。每个Cu(II)原子由来自两个对称相关的席夫碱2-{[2-(异丙基氮鎓基)乙基]亚氨基甲基}-6-甲氧基苯酚盐(L)配体的两个酚氧原子和两个亚胺氮原子以扭曲的平面正方形几何构型四配位。铵基团参与形成N-H⋯O和N-H⋯N氢键,这些氢键将一个二价阳离子和两个阴离子连接成一个电中性簇。当考虑到金属与顶端位置硫氰酸根阴离子之间距离为2.910 (5) Å的非常弱的Cu-N相互作用时,二级配位多面体是一个非常拉长的CuN₄O₂八面体。
