The dinuclear complex in the title compound, [Mn(2)(C(16)H(6)N(2)O(8))(H(2)O)(10)]·4H(2)O, lies on an inversion center. Two delocalized carboxyl-ate groups are each connected in a monodentate fashion to two similar penta-aqua-manganese units, whereas the other two localized carboxyl-ate groups are uncoordinated. The metal ion has octa-hedral coordination, with the O atom of a carboxyl-ate group and three coordinated water mol-ecules forming the equatorial plane [Mn-O(COO) = 2.143 (4) Å] and two water mol-ecules occupying the axial positions. The architecture is further consolidated by extensive hydrogen bonds for which coordinated water mol-ecules serve as donors or acceptors.
标题化合物[Mn₂(C₁₆H₆N₂O₈)(H₂O)₁₀]·4H₂O中的双核配合物位于一个对称中心上。两个离域的羧酸根基团分别以单齿方式连接到两个相似的五水合锰单元上，而另外两个定域的羧酸根基团未配位。金属离子具有八面体配位，一个羧酸根基团的O原子和三个配位水分子形成赤道平面[Mn - O(COO) = 2.143(4) Å]，两个水分子占据轴向位置。通过广泛的氢键进一步巩固了该结构，其中配位水分子充当供体或受体。
