The molecule of the title compound, [Sb(C6H5)3(C7H6NO2)2], is located on a twofold axis defined by the metal center and two C atoms of a coordinated phenyl group. The Sb center has a slightly distorted trigonal-bipyramidal geometry, with the axial positions occupied by the O atoms of symmetry-related 2-hydroxybenzaldehyde oximate ligands. An intramolecular O—H⋯N interaction is present. The is stabilized by C—H⋯O interactions.

Salicylaldoxime (0.4 mmol) was added to a methanol solution of sodium (0.4 mmol) and heated under reflux for 0.5 h. To this solution was added triphenylantimony dichloride (0.2 mmol) in benzene and the mixture was refluxed for 5 h, cooled and filtered. The filtrate was evaporated in vacuo. The obtained solid was recrystallized from dichloromethane-petroleum ether. (yield 86%. m.p.431k). Anal. Calcd (%) for C32H27N2O4Sb (Mr = 625.33): C, 61.46; H, 4.35; N, 4.48; O,10.23. Found (%): C, 61.47; H, 4.40; N, 4.46; O,10.26.
The C—H and O—H H atoms were positioned with idealized geometry (O—H = 0.82 Å and C—H = 0.93 Å) and were refined using a riding model approximation with Uiso(H) = 1.2 Ueq(C, O).The final difference map showed a high residual peak (1.38 e Å-3) at a distance of 0.35 Å from H17.
Among numerous multidentate organic ligands,
are of particular importance, because of their remarkable structural diversity and biological implications. As a continuation of our interest in this area, we have synthesized the title complex. The molecular structures of the compound is depicted in Fig.1. The antimony atom in the compound is five-coordinate, and its geometries is represented as a distorted trigonal bipyramid. The Sb—O bond distance of 2.078 (2) Å is similar to that reported by Wang (Wang et al., 2004; 2.094 (2)Å) . The Sb—C bond distances [2.102 (3) Å; 2.097 (5) Å] fall in the normal range for Sb—C(phenyl) bonds. In the molecules are linked by C—H···O hydrogen bonds.For related structures, see: Wang et al. (2004); Sharutin et al. (2004).

Among numerous multidentate organic ligands, oximes are of particular importance, because of their remarkable structural diversity and biological implications. As a continuation of our interest in this area, we have synthesized the title complex. The molecular structures of the compound is depicted in Fig.1. The antimony atom in the compound is five-coordinate, and its geometries is represented as a distorted trigonal bipyramid. The Sb—O bond distance of 2.078 (2) Å is similar to that reported by Wang (Wang et al., 2004; 2.094 (2)Å) . The Sb—C bond distances [2.102 (3) Å; 2.097 (5) Å] fall in the normal range for Sb—C(phenyl) bonds. In the crystal structure, molecules are linked by C—H···O hydrogen bonds.
