In the title coordination polymer, [Nd₂(C₁₀H₈O₄)₃(H₂O)₂]_n, each of the two Nd^III ions is nine-coordinated by eight O atoms from six different 2,2′-(m-phenylene)diacetate (pda) bivalent anions and by one O atom from a water molecule, forming a distorted tricapped trigonal–prismatic coordination geometry. Eight Nd^III ions and 12 pda ligands form a large [Nd₈(pda)₁₂] ring, and four Nd^III ions and six pda ligands form a small [Nd₄(pda)₆] ring. These rings are further connected by the coordination interactions of pda ligands and Nd^III, generating a three-dimensional supramolecular framework.

Comment top

Lanthanide coordination polymers have shown versatile structural architectures, accompanied with desirable properties, like luminescence, magnetism, catalysis, gas adsorption and separation (Xiao et al., 2008; Lv et al., 2010). In order to extend our investigations in this field, we chose 1,3-phenylendiacetic acid (pda) as a functional ligand and synthesized the lanthanide coordination polymer [Nd₂(pda)₃(H₂O)₂]_n, the structure of which is reported here.

The title compound is isotypic with its Ce analogue (Gao et al., 2011). The asymmetric unit of the title complex (Fig. 1) contains two crystallographically unique Nd^III ions, three pda ligands, and two coordinated water molecules. Both Nd1 and Nd2 are nine-coordinated within a distorted tricapped trigonal-prismatic geometry. The nine coordination sites are occupied by one O atom from a water molecule and eight O atoms from six different pda anions. The Nd—O bond lengths in the title complex are in the range 2.377 (2)–2.749 (2) Å, which is comparable to those reported for other Nd complexes with oxygen environment around the central metal (Xiao et al., 2008; Wang et al., 2009). The pda ligands adopt two coordination modes, viz. µ₄-hexadentate and µ₄-pentadentate. Eight Nd^III ions and twelve pda ligands form a large [Nd₈(pda)₁₂] ring, whereas four Nd^III ions and six pda ligands form a small [Nd₄(pda)₆] ring (Fig. 2). These rings are further connected by the coordination interactions of pda ligands and Nd^III to generate a three-dimensional supramolecular framework (Fig. 2).

Experimental top

To a solution of neodymium nitrate hexahydrate (0.088 g, 0.2 mmol) in water (5 ml) was added an aqueous solution (5 ml) of the ligand (0.058 g, 0.3 mmol) and a drop of triethylamine. The reactants were sealed in a 25-ml Teflon-lined stainless-steel Parr bomb. The bomb was heated at 433 K for 3 d. Upon cooling, the solution yielded single crystals of the title complex in ca 75% yield. Anal./calc. for C₃₀H₂₈Nd₂O₁₄: C, 39.99; H, 3.13; found: C, 40.43; H, 3.47.

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.
