Aqua(dipicolinato‐κ3O,N,O′)(1H‐imidazole‐κN3)(1,10‐phenanthroline‐N,N′)manganese(II)

In the title compound, Mn(C₇H₃NO₄)(C₃H₄N₂)(C₁₂H₈N₂)(H₂O)], the Mn^II centre is surrounded by one bidentate phenanthroline ligand Mn—N = 2.383 (3) and 2.421 (3) Å], one tridentate dipicolinate ligand Mn—N = 2.300 (3) Å, and Mn—O = 2.300 (2) and 2.357 (2) Å], one monodentate imidazole ligand Mn—N = 2.238 (3) Å] and one water molecule Mn—O = 2.157 (3) Å]. It displays a distorted pentagonal‐bipyramidal geometry, with neighbouring angles within the equatorial plane ranging from 68.05 (9) to 77.48 (10)°. 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 π–π stacking interactions involving the phenanthroline rings.
