The title compound, [Ho2(C4H4O4)(C8H4O4)2]n, was synthesized hydrothermally. The Ho atom is coordinated by four O atoms from four benzene-1,4-dicarboxylate (BDC) anions and four O atoms from three succinate anions, in a distorted square-antiprismatic coordination geometry. The antiprisms are bridged by the benzene-1,4-dicarboxylate and succinate anions, into a three-dimensional coordination network. The succinate anions are located on centres of inversion.

A mixture of HoCl3.6H2O (2.00 mmol, 0.74 g), benzene-1,4-dicarboxylic acid (1.0 mmol, 0.16 g), succinic acid (1.0 mmol, 0.10 g), NaOH (6.0 ml, 1 mol/L) and H2O (20.0 ml) was heated in a 35 ml stainless steel reactor with a Teflon liner at 453 K for 48 h. The column-like crystals were filtered and washed with ethanol. Yield: 30% based on Ho.
H atoms were included at calculated positions and treated as riding atoms, with C—H distances of 0.93–0.97 Å and Uiso(H) = 1.2Ueq(C)].
The title compound, (I), is isostructural with its [M2(C8H4O4)2(C4H4O4)]n [M = Gd (Wang & Li, 2005), Dy ((Li & Wang, 2005), Nd (Li et al., 2006) and Er (He et al., 2006)] analogues. The Ho3+ ion is located at the center of a distorted square antiprism and is coordinated by four oxygen atoms from four benzene-1,4-dicarboxylate anions and four oxygen atoms from three succinate anions (Fig. 1). The Ho—O bond distances ranging from 2.2851 (2) to 2.5764 (16) Å.
The succinate anions are located on centres of inversion and acts as a bis-chelating ligands for each two symmetry related Ho atoms. Each of the four oxygen atom are additionally connected by Ho atoms into layers which are parallel to the (001) plane. These layers are connected via the benzene-1,4-dicarboxylate anions into a three-dimensional coordination network.

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. |

The title compound, (I), is isostructural with its [M2(C8H4O4)2(C4H4O4)]n [M = Gd (Wang & Li, 2005), Dy ((Li & Wang, 2005), Nd (Li et al., 2006) and Er (He et al., 2006)] analogues. The Ho3+ ion is located at the center of a distorted square antiprism and is coordinated by four oxygen atoms from four benzene-1,4-dicarboxylate anions and four oxygen atoms from three succinate anions (Fig. 1). The Ho—O bond distances ranging from 2.2851 (2) to 2.5764 (16) Å.
The succinate anions are located on centres of inversion and acts as a bis-chelating ligands for each two symmetry related Ho atoms. Each of the four oxygen atom are additionally connected by Ho atoms into layers which are parallel to the (001) plane. These layers are connected via the benzene-1,4-dicarboxylate anions into a three-dimensional coordination network.
