In the title compound, [Mn(C(7)H(3)NO(4))(C(3)H(4)N(2))(C(12)H(8)N(2))(H(2)O)], the Mn(II) centre is surrounded by one bidentate phenanthroline ligand [Mn-N = 2.383 (3) and 2.421 (3) A], one tridentate dipicolinate ligand [Mn-N = 2.300 (3) A, and Mn-O = 2.300 (2) and 2.357 (2) A], one monodentate imidazole ligand [Mn-N = 2.238 (3) A] and one water molecule [Mn-O = 2.157 (3) A]. It displays a distorted pentagonal-bipyramidal geometry, with neighbouring angles within the equatorial plane ranging from 68.05 (9) to 77.48 (10) degrees . Intermolecular O-H...O hydrogen bonds link the molecules into infinite chains. The chains are crosslinked by hydrogen bonds involving the carboxyl O atoms of the dipicolinate ligand and the protonated imidazole N atom, leading to an infinite two-dimensional network sheet packing mode. The complete solid-state structure can be described as a three-dimensional supramolecular framework, stabilized by these intermolecular hydrogen-bonding interactions and pi-pi stacking interactions involving the phenanthroline rings.
在标题化合物[Mn(C₇H₃NO₄)(C₃H₄N₂)(C₁₂H₈N₂)(H₂O)]中，Mn(II)中心被一个双齿菲咯啉配体[Mn-N = 2.383(3) Å和2.421(3) Å]、一个三齿吡啶二甲酸配体[Mn-N = 2.300(3) Å，且Mn-O = 2.300(2) Å和2.357(2) Å]、一个单齿咪唑配体[Mn-N = 2.238(3) Å]和一个水分子[Mn-O = 2.157(3) Å]所包围。它呈现出扭曲的五角双锥几何构型，赤道平面内相邻角度范围为68.05(9)至77.48(10)度。分子间的O-H...O氢键将分子连接成无限长链。这些链通过涉及吡啶二甲酸配体的羧基O原子和质子化咪唑N原子的氢键相互交联，形成无限的二维网络片状堆积模式。完整的固态结构可描述为三维超分子框架，通过这些分子间氢键相互作用和涉及菲咯啉环的π-π堆积相互作用得以稳定。
