摘要

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) angstrom], one tridentate dipicolinate ligand [ Mn - N = 2.300 ( 3) angstrom, and Mn - O = 2.300 ( 2) and 2.357 ( 2) angstrom], one monodentate imidazole ligand [ Mn - N = 2.238 ( 3) angstrom] and one water molecule [ Mn - O = 2.157 ( 3) angstrom]. 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 center dot center dot center dot O hydrogen bonds link the molecules into in nite 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 in nite 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.
