The title compound, [Cu(C(10)H(24)N(4))(H(2)O)(2)]CH(3)(CH(2))(10)CO(2)·2H(2)O, consists of one cationic copper(II) complex, two dodeca-noate anions and two water solvent mol-ecules. The Cu(II) atom is located on an inversion center and is chelated by the four aza N atoms of the neutral 1,4,8,11-tetra-aza-cyclo-tetra-decane (cyclam) ligand and by two water mol-ecules in axial positions, giving an octa-hedral coordination geometry, distorted as a consequence of the Jahn-Teller effect. The uncoordinated water mol-ecules link the complex cations and the dodeca-noate counter-ions through O-H⋯O hydrogen bonding, forming a layer structure parallel to (001). Inter-molecular N-H⋯O inter-actions also occur.
标题化合物[Cu(C₁₀H₂₄N₄)(H₂O)₂][CH₃(CH₂)₁₀CO₂]₂·2H₂O由一个阳离子铜（II）配合物、两个十二烷酸根阴离子和两个水分子溶剂分子组成。铜（II）原子位于一个对称中心上，由中性的1,4,8,11-四氮杂环十四烷（环胺）配体的四个氮原子螯合，并在轴向位置由两个水分子配位，形成八面体配位几何构型，由于 Jahn-Teller 效应而发生畸变。未配位的水分子通过O-H⋯O氢键连接配合物阳离子和十二烷酸根抗衡离子，形成平行于(001)的层状结构。分子间还存在N-H⋯O相互作用。
