Diaquabis(5-carboxy-2-propyl-1H-imidazole-4-carboxylato-[kappa]2N3,O4)magnesium(II) 3.5-hydrate

Abstract top

In the title complex, [Mg(C8H9N2O4)2(H2O)2]·3.5H2O, the MgII atom is six-coordinated by two N,O-bidentate 5-carboxy-2-propyl-1H-imidazole-4-carboxylate ligands and two water molecules, forming a distorted octahedral environment. The complex molecules are linked into a three-dimensional network by N-H...O and O-H...O hydrogen-bonding interactions. The propyl groups are disordered over two sites, with site occupancies of 0.755 (7):0.245 (7) and 0.556 (13):0.444 (13).

Comment top

Imidazole-4,5-dicarboxylate ligands with efficient N,O-donors have been been widely used to obtain new complexes with excellent properties (Sengupta et al., 2001; Song et al.,2010; Wang et al., 2004; Yan et al., 2010). Bearing this in mind, we introduced Mg(CH3CO2)2 and 2-propyl-1H-imidazole-4,5-dicarboxylic acid into reaction so as to obtain a new MgII complex.

As illustrated in Fig. 1, the title complex molecule contains one MgII ion, two mono-deprotonated 2-propyl-1H-imidazole-4,5-dicarboxylate ligands, two coordinated water molecules and three and half uncoordinated water molecules. The Mg II atom is six-coordinated by two N,O-bidentate ligands and two water molecules in a slightly distorted octahedral environment. Both ligands coordinate through N atoms and carboxylate O atoms in a bidentate chelate fashion, forming two five-membered Mg, O, C, C, N rings. Uncoordinated solvent water molecules are located in cavities of the three-dimensional network, participating in N—H···O and O—H···O hydrogen bonds, which contribute to the stability of the network. The two propyl residues are disordered over two sites, with site occupancies of 0.755 (7):0.245 (7) and 0.556 (13):0.444 (13).

Experimental top

The title compound was prepared by the hydrothermal reaction of Mg(CH3CO2)2 (0.5 mmol, 0.07 g) and 2-propyl-1H-imidazole-4,5-dicarboxylic acid (0.5 mmol, 0.99 g) in 15 ml of H2O solution. The reaction was performed in a Teflon-lined autoclave (20 ml), which was heated at 433 K for 2 d. Crystals of the title compound were obtained by slow evaporation of the solvent at room temperature.

Refinement top

C- and N-bound H atoms were placed at calculated positions and were treated as riding atoms, with C—H = 0.97 (CH2) and 0.96 (CH3) 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 map and refined as riding, with O—H = 0.85 Å and Uiso(H) = 1.2Ueq(O). H atoms of carboxyl groups were located in a difference map and refined as riding, with O—H = 0.82 Å and Uiso(H) = 1.5Ueq(O).
