The tetra-nuclear copper(II) title complex, Cu(4)Cl(2)(OH)(4)(C(10)H(8)N(2))(4)(2)·6H(2)O, has a crystallographically imposed centre of symmetry. The metal atoms display a distorted tetragonal-pyramidal coordination geometry, and are linked by two μ(2)- and two μ(3)-hydroxo groups, assuming a chair-like conformation for the Cu(4)O(2) core. In the crystal, the complex mol-ecules are linked into a three-dimensional network by inter-molecular O-H⋯O, O-H⋯Cl, C-H⋯O and C-H⋯Cl hydrogen bonds and π-π stacking inter-actions with centroid-centroid separations of 3.724 (2) and 3.767 (3) Å.
四核铜（II）标题配合物Cu₄Cl₂(OH)₄(C₁₀H₈N₂)₄₂·6H₂O具有晶体学上的对称中心。金属原子呈现出扭曲的四方锥配位几何构型，并通过两个μ₂ - 和两个μ₃ - 羟基相连，Cu₄O₂核呈椅状构象。在晶体中，配合物分子通过分子间的O - H⋯O、O - H⋯Cl、C - H⋯O和C - H⋯Cl氢键以及质心 - 质心间距为3.724（2）和3.767（3）Å的π - π堆积相互作用连接成三维网络。
