Abstract top

The crystal structure of the title complex, [Gd(C8H3NO6)(C8H4NO6)(C12H8N2)]n, contains polymeric chains made up of GdIII atoms, 1,10-phenanthroline and fully or half-deprotonated 5-nitrobenzene-1,3-dicarboxylic acid (H2L) ligands. The GdIII atom is coordinated in a distorted bicapped trigonal-prismatic fashion by six O atoms from two HL- and three L2- ligands, and by two N atoms from the 1,10-phenanthroline ligand. The L2- ligands bridge the Gd-phenanthroline units, forming chains running parallel to [100]. O-H...O hydrogen bonding as well as [pi]-[pi] stacking interactions with an interplanar distance of 3.599 (2) Å assemble neighboring polymeric chains.

Comment top

Recently, we became interested in the nature of π–π stacking as it plays an important role in some biological processes (Deisenhofer & Michel, 1989). A series of metal complexes incorporating different aromatic ligands has been prepared and their crystal structures provide useful information about π–π stacking (Wu et al., 2003; Pan & Xu, 2004; Li et al., 2005 Qiu et al., 2009). As part of our ongoing investigations, the title complex, (I), incorporating 1,10-phenanthroline, has been prepared.

As depicted in Fig. 1, the GdIII atom has a distorted bicapped trigonal-prismatic coordination, defined by six O atoms from two 1-carboxy-5-nitro-3-benzoate (HL-, where L is 5-nitro-1,3-benzenedicarboxyic acid) and three 5-nitro-1,3-benzenedicarboxylate ligands (L2-), and two N atoms from the 1,10-phenanthroline ligand. The L2- ligands link Gd-phenanthroline moieties, forming an infinite polymeric chain running along [100]. The HL- and L2- ligands in this complex have two different coordination modes: the first ligand uses one of its carboxylate groups to link one GdIII ions in a chelating coordination mode, the other carboxylate group links two GdIII ions in a bis-monodentate coordination mode, whereas the other ligand uses its carboxylate groups to link two GdIII ions in a bridging coordination mode. In the chain, the closest Gd···Gd separation is 4.333 (3) Å. These chains interact with each other by π–π stacking of adjacent phenanthroline groups (interplanar distance of 3.599 (2) Å). O—H···O hydrogen bonding interactions between carboxyl and carboxylate groups of neighbouring ligands help to consolidate the structure (Table 1; Fig. 2).

Experimental top

A sample of Gd2O3 (0.0732 g, 0.20 mmol), 5-nitro-1,3-benzenedicarboxylic acid (0.1015 g, 0.50 mmol), 1,10-phenanthroline (0.0991 g, 0.50 mmol) and distilled water (8 ml) were mixed in a Teflon-lined stainless steel vessel with 15 ml capacity. The mixture was heated under autogenous pressure at 393 K for 48 h and cooled slowly to room temperature.

Refinement top

The C— and O—bound H atoms were included in the riding-model approximation, with C—H = 0.97 Å and O—H = 0.82 Å, and Uiso(H) = 1.2Ueq(C) and 1.5Ueq (O). The highest and the deepest hole the final difference Fourier map are located 1.03 and 1.05 Å, respectively, from the Gd1 atom.

Special details top

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