In the title complex, [Pb(C8H9N2O4)2(H2O)2]n, the eight-coordinate PbII atom lies on a twofold rotation axis and adopts a slightly distorted square-anti­prismatic N2O6 coordination geometry. The ligand donor atoms are the tertiary N atoms of the imidazole rings and the carboxyl­ate O atoms of two chelating 5-carb­oxy-2-propyl-1H-imidazole-4-carboxyl­ate ligands, the carb­oxy O atoms of two additional imidazole ligands and two water O atoms. The carb­oxy O and the N,O-chelate systems also link adjacent PbII atoms, forming a two-dimensional layer structure, with four individual PbII atoms located at the corners of a square. These layers are further inter­connected by an extensive array of O—H⋯O and N—H⋯O hydrogen bonds into a three-dimensional network.

It is well known that 4,5-imidazoledicarboxylic acid, a rigid N-heterocyclic dicarboxylic acid has great potential as a ligand in coordination complexes and for hydrogen bond formation. Imidazoledicarboxylate complexes have been found to exhibit useful properties, such as magnetism and porosity (Cao et al., 2002; Rajendiran et al., 2003). We have therefore reacted the 2-propyl-1H-imidazole-4,5 dicarboxylic acid ligand with Pb(NO3)2 under hydrothermal conditions to obtain a new PbII complex and its structure is reported here.

In the title complex, [Pb(C8H9N2O4)2(H2O)2]n, the eight coordinate PbII atom lies on a two-fold rotation axis and adopts a slightly distorted square-antiprismatic N2O6 coordination geometry. The ligand donor atoms are the N1 atoms of the imidazole rings and the carboxylate O1 atoms of two chelating 5-carboxy-2-propyl-1H-imidazole-4- carboxylato ligands, the O4 carboxy oxygen atoms of two additional imidazole ligands and two O5 water molecules. The O1 and N1 atoms of the chelate systems also link adjacent PbII centres forming a two-dimensional layer structure, with four individual PbII atoms located at the corners of a square. These layers are further interconnected by an extensive array of O—H···O and N—H···O hydrogen bonds into a three-dimensional network.

Experimental top

A mixture of Pb(NO3)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 was sealed in an autoclave equipped with a Teflon liner (25 ml) and then heated at 373k for 3 days. Crystals of the title compound were obtained by slow evaporation of the solvent at room temperature.

Refinement top

Carbon and nitrogen bound H atoms were placed at calculated positions and were treated as riding on the parent C or N atoms with C—H = 0.93 Å, N—H = 0.86 Å, and with Uiso(H) = 1.2 Ueq(C, N). H atoms of the water molecule were located in a difference map and were allowed to ride on the parent atom, with Uiso(H)=1.2 Ueq.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
