In the title complex, [Co(C8H9N2O4)2(H2O)2]·2C3H7NO, the CoII cation (site symmetry ) is six-coordinated by two 5-carboxy-2-propyl-1H-imidazole-4-carboxylate ligands and two water molecules in a distorted octahedral environment. In the crystal structure, the complex molecules and dimethylformamide solvent molecules are linked by extensive O-HO and N-HO hydrogen bonding into sheets lying parallel to (21).
For our past work based on the 2-propyl-1H-imidazole-4,5-carboxylate (H3pimda) ligand, see: Yan et al. (2010); Li et al. (2010a,b,c,d); Song et al. (2010); He et al. (2010); Fan et al. (2010). For Co complexes of a similar ligand, see: Lu et al. (2008); Wang et al. (2004).
