In the title compound, [Lu2(C8H4O4)2(C2O4)(H2O)2]n, the Lu3+ cations are each coordinated by eight O atoms of four terephthalate anions, one oxalate anion and one aqua ligand to complete a distorted square-anti­prismatic geometry. They are bridged by the terephthalate ligands, generating a three-dimensional framework, which is further stabilized by the oxalate ligands. The terephthalate ions and oxalate ions are all located on centers of inversion.

Comment top

In the title compound, the asymmetric unit consists of one Lu3+ cation, one half of oxalate anion, two half of terephthalate anions and one aqua ligand. The Lu atoms are each coordinated by eight O atoms of four terephthalate anions, one oxalate anion and one aqua ligand to complete a distorted square antiprismatic geometry (Fig.1). The Lu–O distances are in the range of 2.195 (2)–2.825 (3) Å. The two crystallography independent terephthalate (tp) anions are both located on the center of symmetry and exhibit different types of coordination mode to Lu atoms. The tp1 (O1 to O2, C1 to C4) anion functions as chelating-bridging tridentate ligand, two carboxylate oxygen atoms chelate one Lu atom in which one oxygen atom additionally bonded to another Lu atom with the Lu···Lu seperation of 4.245 (2) Å. Then two edge-shared [LuO8] polyhedra are bridged by the bidentate tp2 (O3 to O4, C5 to C8) ligands to generate one-dimensional chains along [010] direction. Thus the chains are linked by the tp1 and tp2 ligands into a three-dimensional framework. Bond lengths and angles within the terephthalate anions exhibit normal values (Daiguebonne et al., 2006). The oxalate ions are also located on centers of inversion and act as double bidentate (tetradentate) ligand in the linear chain which connect the edge-shared [LuO8] polyhedra along [100] direction to stabilize the three-dimensional framework. The aqua ligands donate hydrogen atoms to terephthalate oxygen atoms O2 and O3 to form hydrogen bonds.

Experimental top

A mixture of LuCl3.6H2O (1.00 mmol, 0.39 g), oxalic acid (0.50 mmol, 0.05 g), terephthalic acid (0.50 mmol, 0.09 g), NaOH (2.00 mmol, 0.08 g) and H2O (10.0 ml) was heated in a 23 ml stainless steel reactor with a Teflon liner at 443 K for 48 h. A small amount of colorless column-like crystals were filtered and washed with water and acetone.

Refinement top

H atoms attached to C atoms were included at calculated positions and treated as riding atoms [C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C)]. The water H atoms were found in a difference map, relocated in idealized positions (O—H = 0.85 Å) and refined as riding atoms with Uiso(H) = 1.5Ueq(O). The highest density peak and deepest hole are located 0.88 Å and 0.90 Å from atom Lu.

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.
