Abstract top

The structure of the title compound, [Sb(C6H5)3(C7H6NO2)2], contains two independent molecules of similar configuration. The Sb atoms exhibit a distorted trigonal-bipyramidal geometry with the O atoms of two carboxylate groups in the axial positions and the C atoms of the phenyl groups in the equatorial positions. In the crystal structure, molecules are connected by intermolecular N-H...O and N-H...N hydrogen-bonding interactions forming a chain structure along [100].

Comment top

The organoantimony(V) derivatives have attracted considerable attention due to the significant antimicrobial properties as well as antitumor activities recently. As a part of our ongoing investigations in ths field we have synthesized the title compound and determined its crystal structure. The crystal structure of the title compound which contains two independent molecules is shown in Fig.1 The Sb atom in both molecules assumes a distorted trigonal bipyramidal coordination geometry, provided by two carboxylate groups at the axial positions and three phenyl groups at the equatorial positions. The Sb—O bond distances (Sb1—O1 = 2.091 (4) Å; Sb1—O3 = 2.114 (4) Å; Sb2—O5 = 2.098 (5) Å; Sb2—O7 = 2.114 (5) Å) are comparable to those found in organoantimony arylhydroxmates (Wang et al. 2005). The Sb—C bond distances (Sb1—C15 = 2.121 (6) Å; Sb1—C21 = 2.115 (5) Å; Sb1—C27 = 2.115 (6) Å; Sb2—C47 = 2.101 (7) Å; Sb2—C53 = 2.074 (8) Å; Sb2—C59 = 2.068 (8) Å) of the compound lie within the normal range for Sb—C (phenyl) bonds (2.10–2.13 Å). In the crystal packing, molecules are linked by intermolecular N—H···O hydrogen bonds (Fig.2, Table 1,)

Experimental top

The reaction was carried out under nitrogen atmosphere. 4- aminobenzoic acid (2 mmol) and sodium ethoxide (2.4 mmol) were added to a stirred solution of methanol (30 ml) in a Schlenk flask and stirred for 0.5 h. Triphenylantimony dichloride (1 mmol) was then added to the reactor and the reaction mixture was stirred for 12 h at room temperature. The resulting clear solution was evaporated under vacuum. The product was crystallized from dichloromethane/methanol (1:1) to yield colourless blocks (yield 86%. m.p.521 K). Anal. Calcd (%) for C32H27O4Sb1N2 (: C, 61.46; H, 4.35; O, 10.23; Sb, 19.47. Found (%): C, 61.40; H, 4.42; O, 10.28; Sb, 19.43

Refinement top

The C—H and N—H hydrogen atoms were positioned with idealized geometry and were refined isotropic with Uiso(H) = 1.2 Ueq(C, O) for all H atoms using a riding model with N—H = 0.86 Å and C—H = 0.93 Å.
