Abstract top

The title complex, [Nd2(C8H3NO6)2(C8H4NO6)2(H2O)6]·2H2O, consists of dimeric units related by an inversion center. The NdIII atom is nine-coordinated by three O atoms from water molecules and six from carboxylate atoms. The 1,2-dicarboxylate acid molecules are in a single and double deprotonation stage and exhibit two coordination modes, viz. [mu]2-([kappa]4, O1: O2: O2: O3) and [mu]1-([kappa]2, O2: O3), which are responsible for the dimeric structure framework. The dimeric structure is then assembled into a three-dimensional supramolecular framework via O-H...O hydrogen bonds.

Comment top

We report here a neodymium complex based on 3-nitrobenzene-1,2- dicarboxylic acid ligands. X-ray diffraction crystal structure analysis reveals that the complex forms a structure [Nd2(C8H4NO6)2(C8H3NO6)2 (H2O)6].2H2O, consisting of dimeric units related by an inversion center. The compound is isostructural to the corresponding La compound reported by Xiong & Qi (2007).

In the title complex, the central neodymium center is coordinated by nine oxygen atoms (Fig. 1), the coordination geometry of which can be described as distorted tricapped trigonal-prismatic. Six of the nine coordinating oxygens are from the two coordinating H2NPA (3-nitrobenzene-1,2-dicarboxylic acid) ligands and the remaining three from water molecules. 3-Nitrobenzene-1,2-dicarboxylic acid ligands exhibit two coordination modes (Fig. 2), which can be classified as µ2-(κ4, O1: O2: O2: O3) and µ1-(κ2, O2: O3). In one unit of the complex, there are four H2NPA anions. Two (NPA2-) ions are dianionic, so the other (HNPA-) anion is monoprotonated to maintain electroneutrality. Correspondingly, two types of coordination modes of H2NPA ligands exist in the structure.

Experimental top

A mixture of neodymium chloride hexahydrate (0.03585 g, 0.1 mmol), sodium hydroxide (0.0080 g, 0.2 mmol), 3-nitrobenzene-1,2-dicarboxylic acid (0.0211 g, 0.1 mmol), and CH3OH (20 mL) was placed in a Parr Teflon-lined stainless stell vessel (25 ml), which was sealed and heated at 443.15 K for 4 days. Then the vessel was cooled to 373.15 K at a rate of 5 K h-1 and subsequently slowly to room temperature. Purple, block single crystals suitable for X-ray diffraction were obtained.

Refinement top

H atoms bonded to C atoms were placed geometrically and treated as riding, with C—H distances 0.93 Å for aryl type H-atoms, respectively with Uiso(H) = 1.2Ueq(C). H atoms attached to O atoms were found in a difference Fourier synthesis and were refined using a riding model, with the O–H distances fixed as initially found and with Uiso(H) values set at 1.2 Ueq(O). Positive and negative residual densities close to oxygen positions are most probably due to different orientational conformations of water molecules or hydroxyl groups. The most likely orientations were retained.

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.
