Abstract top

In the planar (r.m.s. deviation = 0.027 Å) title compound, [Hg(C7H5O2)Cl], the HgII atom shows a typical linear coordination by a C atom of the benzene ring and a Cl atom. Intermolecular O-H...O hydrogen bonds are present in the crystal structure, resulting in chains propagating along the b axis. The crystal studied was a non-merohedral twin, with a twin ratio of 0.802 (2):0.198 (2).

Comment top

Cyclometallated compounds have attracted much research interest owing to theirs utility in synthesis, catalysis and materials (Gruter et al., 1995; Dupont et al., 2005). Among them, cyclomercurated compounds are easy to prepare through a C–H activation process and are stable but reasonably reactive (Wu et al., 2001; Ryabov et al., 2003).

In the planar title compound (Fig. 1), the mercury(II) atom shows a typical linear coordination geometry with a carbon atom of the benzene ring and the chloride atom in trans position. O2–Hg1 distance (3.047 (2) Å) is much longer than those of the related Hg(II) complex (Xu et al., 2009). The C–Hg and Hg–Cl bond distances are within normal ranges. The C3–Hg1–Cl1 angle is 179.1 (4) °. Intermolecular O—H···O hydrogen bonds are present in the crystal structure (Table 1), resulting in a one-dimensional supramolecular architecture (Fig.2).

Experimental top

The title compound was prepared from the p-hydroxybenzaldehyde with Hg(OAc)2 and subsequent treatment with LiCl and recrystallized from dichloromethane-petroleum ether solution at room temperature to give (I) as colorless crystals suitable for single-crystal X-ray diffraction.

Refinement top

All H atoms were placed in geometrically idealized positions, with C—H = 0.93–0.96 Å, O—H = 0.82–0.85 Å and N—H = 0.86 Å. Uiso(H) = 1.2Ueq(C,N), and 1.5Ueq(O).

The structure is a non-merohdral twin. The twin law, as given by PLATON (Spek, 2009), is (-1 0 0, 0 - 1 0, 2 0 1), which lowered the R1 index from 0.116 to 0.039.

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.
