Chlorido(2-chloro­nicotinato)triphenyl­anti­mony(V)

Abstract

In the title complex, [Sb(C6H5)3(C6H3ClNO2)Cl], the Sb center has a close to ideal trigonal-bipyramidal geometry, with the phenyl ligands in equatorial positions and the chloride and a carboxyl­ate O atom in axial positions. Weak C—H(...)O contacts generate dimeric units via crystallographic inversion centres.

Comment

The triphenylantimony(V) acetylferroceneoxime structure shows some in vitro antitumor activity (Yin et al. 2008). The title compound may show similar activities. A similar compound was synthesized (Chaudhari et al.2007). The crystal structure of complex I (Fig. 1) consists of dimeric units, (Fig. 2) generated through weak intermolecular C—H···O hydrogen bonds via crystallographic inversion centres (Table 2). The sum of the equatorial angles C7—Sb1—C13, C13—Sb1—C19 and C19—Sb1—C7 is 359.98° and the corresponding axial angle Cl2—Sb1—O1 is 177.56 (6)° (Table 1). The distance Sb—O1 2.114 (2) Å is shorter than the range of short Sb—O distances 2.119 (3) - 2.133 (3) Å, and shorter than the range of the long Sb—O distances between 3.012 (6) and 3.112 (4) Å from related literature (Chaudhari et al.2007). The Sb1—O2 distance of 2.898 (2) Å in the title complex is shorter than the sum of the van der Waals radii for Sb and O (3.2 Å), but much longer than the covalent bond Sb–O1 (2.114 (2) Å). So it can be considered that atom O2 does not make any significant contact with the Sb1 atom.

Experimental

2-chloronicotinic acid (0.044 g, 0.4 mmol) and sodium methoxide (0.8 ml, 0.4 mmol) was added to a stirring solution containing triphenylantimonydichloride (0.172 g, 0.4 mmol) in toluene (25 ml). After refluxing for 8 h, the colorless solution was obtained and then filtered. The solvent was gradually removed by evaporation under vacuum until the white solid was obtained. The solid was recrystallized from petroleum ether/dichoromethane (1:1) to give colorless crystals.

Refinement

All H atoms were placed in calculated positions, with C—H = 0.93 Å, with Uiso(H) = 1.2 Ueq(C).
