The title complex, [Mn(2)(SO(4))(2)(C(8)H(6)N(4))(H(2)O)(6)], is the second monoclinic polymorph [De Munno et al. (1995 ▶). Inorg. Chem.34, 408-411; Hong et al. (1996 ▶). Polyhedron, 15, 447-452]. The asymmetric unit contains two crystallographically independent half-mol-ecules of the binuclear Mn(II) complex; an inversion centre is located at the centroid of each complex. The two Mn(II) atoms in each complex mol-ecules are bridged by a bis-chelating 2,2'-bipyrimidine (bpym) ligand and each Mn(II) atom is six-coordinated in a considerably distorted octa-hedral environment defined by two N atoms of the bridging bpym ligand and four O atoms from one sulfato anionic ligand and three water mol-ecules. In the crystal, the complex mol-ecules are linked by O-H⋯O hydrogen bonds between the water and sulfato ligands, forming a three-dimensional network.
标题配合物[Mn(2)(SO(4))(2)(C(8)H(6)N(4))(H(2)O)(6)]是第二种单斜多晶型物[德·蒙诺等人（1995年▶）。《无机化学》34，408 - 411；洪等人（1996年▶）。《多面体》，15，447 - 452]。不对称单元包含双核Mn(II)配合物的两个晶体学独立的半分子；一个反演中心位于每个配合物的质心处。每个配合物分子中的两个Mn(II)原子由双螯合的2,2'-联嘧啶（bpym）配体桥连，并且每个Mn(II)原子在由桥连bpym配体的两个N原子以及来自一个硫酸根阴离子配体和三个水分子的四个O原子所定义的明显扭曲的八面体环境中呈六配位。在晶体中，配合物分子通过水和硫酸根配体之间的O - H⋯O氢键相连，形成三维网络。
