In the trinuclear title compound, [Zn(3)Cl(6)(C(13)H(20)N(4))(2)]·2H(2)O, each terminal Zn(II) atom is coordinated by an N(3) donor set from the Schiff base ligands and two Cl atoms in a distorted square-pyramidal geometry. The central Zn(II) atom is tetra-hedrally coordinated by two piperazine N atoms from two Schiff base ligands and two Cl atoms. The piperazine rings adopt chair conformations. In the crystal structure, adjacent complex mol-ecules are linked into a three-dimensional network via N-H⋯O, C-H⋯Cl and C-H⋯O hydrogen bonds. The structure includes two water mol-ecules, one of which is disordered over two positions with occupancies of 0.753 (15) and 0.247 (15).
在三核标题化合物[Zn₃Cl₆(C₁₃H₂₀N₄)₂]·2H₂O中，每个末端Zn(II)原子由席夫碱配体的一个N₃供体基团和两个Cl原子配位，呈扭曲的四方锥几何构型。中心Zn(II)原子由来自两个席夫碱配体的两个哌嗪N原子和两个Cl原子以四面体方式配位。哌嗪环呈椅式构象。在晶体结构中，相邻的配合物分子通过N—H⋯O、C—H⋯Cl和C—H⋯O氢键连接成三维网络。该结构包含两个水分子，其中一个在两个位置上无序，占有率分别为0.753(15)和0.247(15)。
