In the title centrosymmetric tetra-nuclear complex, [Mn(4)(C(12)H(6)O(4))(4)(C(10)H(8)N(2))(4)(H(2)O)(8)]·4H(2)O, two independent Mn(II) ions are coordinated in a slightly disorted octa-hedral environment by two aqua ligands, two naphthalene-1,8-dicarboxyl-ate (1,8-nap) ligands and one bis-chelating 2,2'-bipyridine (2,2'-bipy) ligand. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds into chains along [100]. These chains are further linked by weak π-π inter-actions with centroid-centroid distances in the range of 3.609 (2)-3.758 (1) Å, forming a three-dimensional supra-molecular network.
在标题为中心对称四核配合物[Mn₄(C₁₂H₆O₄)₄(C₁₀H₈N₂)₄(H₂O)₈]·4H₂O中，两个独立的Mn(II)离子在略微扭曲的八面体环境中，通过两个水配体、两个萘-1,8-二羧酸根（1,8-nap）配体和一个双螯合的2,2'-联吡啶（2,2'-bipy）配体进行配位。在晶体中，分子通过分子间O-H⋯O氢键沿[100]方向连接成链。这些链通过弱的π-π相互作用进一步连接，质心-质心距离在3.609 (2)-3.758 (1) Å范围内，形成三维超分子网络。
