In the title complex, [Co(C13H14N3O3)2(H2O)2], the CoII atom has a distorted octahedral coordination, formed by four N atoms from two (±)-2-(5-isopropyl-5-methyl-4-oxo-4,5-dihydro-1H-imidazol-2-yl)nicotinate ligands and two O atoms from two water molecules. Intramolecular N—H⋯O and O—H⋯O hydrogen bonds are present. In the crystal, intermolecular O—H⋯O hydrogen bonds link the complex molecules into a chain along [010].

A solution of Imazapyr acid (0.39 g, 1.5 mmol) in 95% ethanol (15 ml) was added dropwise with stirring at room temperature to a solution of Co(CH3COO)2.4H2O (0.13 g, 0.5 mmol) in 20 ml water. The mixture was stirred at room temperature until it was homogeneous and then sealed in a 25 ml Teflon-lined stainless reactor, which was kept under autogenous pressure at 423 K for 5 h and then slowly cooled to room temperature. After 5 days, red block crystals suitable for X-ray diffraction were separated and washed with water. The product is stable in air and insoluble in water and common organic solvents (yield: 76%). Analysis, calculated for C26H32CoN6O8: C 50.74, H 5.24, N 13.65%; found: C 50.77, H 5.23, N 13.64%.
H atoms on C and N atoms were positioned geometrically and refined using a riding model, with C—H = 0.93–0.98 Å and N—H = 0.86 Å and with Uiso(H) = 1.2(1.5 for methyl)Ueq(C,N). The water H atoms were located in a difference Fourier map and refined as riding atoms, with O—H = 0.85 Å and Uiso(H) = 1.2Ueq(O).
Much effort has been devoted to the synthesis (Bombek et al., 2005; Ellis et al., 2000) and crystal structures (Erre et al., 1998; Fu et al., 2008) of the compounds containing imidazolidinone derivatives during the last few years. One of them is (±)-2-(4-isopropyl-4-methyl-5-oxo-4,5-dihydro-1H-2-imidazol-2-yl) nicotinic acid (Imazapyr acid), which provides efficient metal-chelating ability. Imazapyr acid containing a pyridinecarboxylic acid and an imidazole ring is well known a versatile ligand. The pyridine carboxylic acid has been extensively used in the design of coordination compounds, due to a variety of bonding modes and ability to form strong hydrogen bonds (Chatterjee et al., 1998; Nathan & Mai, 2000; Park et al., 2007; Yang et al., 2002). Imidazole ring, which is one of the polydentate amine ligands, generally coordinates to metal ions using the N atoms as donors. We report here the structure of the title compound.
The molecular structure of the title complex is shown in Fig. 1. The CoII atom exhibits a distorted octahedral geometry, defined by four N atoms from two imazapyr ligands and two O atoms from water molecules (Table 1). The dihedral angle between the two imazapyr planes in the complex is 64.39 (2)°. Intramolecular O—H···O and N–H···O hydrogen bonds are observed between the coordinated water molecules and imazapyr ligands and between the imidazole and carboxylate groups (Table 2). Intermolecular O—H···O hydrogen bonds link the complex molecules into a chain along [0 1 0] (Fig. 2).

Much effort has been devoted to the synthesis (Bombek et al., 2005; Ellis et al., 2000) and crystal structures (Erre et al., 1998; Fu et al., 2008) of the compounds containing imidazolidinone derivatives during the last few years. One of them is (±)-2-(4-isopropyl-4-methyl-5-oxo-4,5-dihydro-1H-2-imidazol-2-yl) nicotinic acid (Imazapyr acid), which provides efficient metal-chelating ability. Imazapyr acid containing a pyridinecarboxylic acid and an imidazole ring is well known a versatile ligand. The pyridine carboxylic acid has been extensively used in the design of coordination compounds, due to a variety of bonding modes and ability to form strong hydrogen bonds (Chatterjee et al., 1998; Nathan & Mai, 2000; Park et al., 2007; Yang et al., 2002). Imidazole ring, which is one of the polydentate amine ligands, generally coordinates to metal ions using the N atoms as donors. We report here the structure of the title compound.
The molecular structure of the title complex is shown in Fig. 1. The CoII atom exhibits a distorted octahedral geometry, defined by four N atoms from two imazapyr ligands and two O atoms from water molecules (Table 1). The dihedral angle between the two imazapyr planes in the complex is 64.39 (2)°. Intramolecular O—H···O and N–H···O hydrogen bonds are observed between the coordinated water molecules and imazapyr ligands and between the imidazole and carboxylate groups (Table 2). Intermolecular O—H···O hydrogen bonds link the complex molecules into a chain along [0 1 0] (Fig. 2).
