Diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-κ²N³,O⁴)manganese(II) 3.5-hydrate

Abstract

Key indicators: single-crystal X-ray study; T = 296 K; mean (C-C) = 0.006 Å; disorder in main residue; R factor = 0.059; wR factor = 0.152; data-to-parameter ratio = 13.2.In the title complex, [Mn(C 8 À ligands (H 2 pimda À = 5-carboxy-2-propyl-1H-imidazole-4-carboxylate) and two water molecules in a distorted octahedral environment. The complete solid-state structure can be described as a three-dimensional supramolecular framework stabilized by a wide range of O-HÁ Á ÁO and N-HÁ Á ÁO hydrogen bonds. The propyl groups of H 2 pimda À are disordered over two sets of sites with refined occupancies of 0.759 (5):0.241 (5) and 0.545 (7):0.455 (7). Related literature ExperimentalCrystal data [Mn(C 8
