Crystals of the title compound were synthesized using hydrothermal method in a 23 ml Teflon-lined Parr bomb. Lanthanum(III) nitrate hexahydrate (216.4 mg, 0.5 mmol), chromium(II) acetate dihydrate (103.1 mg, 0.5 mmol), 4-methyl- benzenesulfonic acid (344.4 mg, 2 mmol), ammonia (0.5 mol/l, 4 ml) and distilled water (10 g) were placed into the bomb and sealed. The bomb was then heated under autogenous pressure up to 443 K over the course of 7 d and allowed to cool at room temperature for 24 h. Upon opening the bomb, a clear colorless solution was decanted from small colorless crystals. These crystals were washed with distilled water followed by ethanol, and allowed to air-dry at room temperature.
H atoms (for H2O) were located in difference syntheses and refined isotropically [O—H = 0.832 (18)–0.89 (4) Å and Uiso(H) = 0.092 (11)–0.12 (2) Å2]. The remaining H atoms were positioned geometrically, with C—H = 0.93 and 0.96 Å, for aromatic and methyl H atoms and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.2 for aromatic H and x = 1.5 for methyl H atoms.
The crystal structure of hexaaquacopper(II) bis(4-methylbenzenesulfonate), (II), has previously been reported (Zhong et al., 2007). The crystal structure determination of the title compound, (I), has been carried out in order to elucidate the molecular conformation and to compare it with that of (II). We report herein the crystal structure of (I).
The asymmetric unit of the title compound, (I), (Fig. 1) contains one half -cation and one anion; the Cr atom lies on an inversion centre, as in (II). The bond lengths and angles (Table 1) are within normal ranges (Allen et al., 1987).
In the crystal structure, intermolecular O—H···O and O—H···S hydrogen bonds (Fig. 2 and Table 2) result in the formation of a supramolecular network structure; an intramolecular C—H···O hydrogen bond is also present, as in (II).
The both compounds, (I) and (II), are isostructural.

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 crystal structure of hexaaquacopper(II) bis(4-methylbenzenesulfonate), (II), has previously been reported (Zhong et al., 2007). The crystal structure determination of the title compound, (I), has been carried out in order to elucidate the molecular conformation and to compare it with that of (II). We report herein the crystal structure of (I).
The asymmetric unit of the title compound, (I), (Fig. 1) contains one half -cation and one anion; the Cr atom lies on an inversion centre, as in (II). The bond lengths and angles (Table 1) are within normal ranges (Allen et al., 1987).
In the crystal structure, intermolecular O—H···O and O—H···S hydrogen bonds (Fig. 2 and Table 2) result in the formation of a supramolecular network structure; an intramolecular C—H···O hydrogen bond is also present, as in (II).
The both compounds, (I) and (II), are isostructural.
