Tetra-p-tolylantimony p-toluenesulfonate was prepared from penta-p-tolylant
imony and tri-p-tolylantimony bis(p-toluenesulfonate). According to X-ray d
ata the configuratuion of the antimony atom in this complex is a trigonal b
ipyramid with the axially located oxygen atom of the sulfo group. The bond
lengths (Angstrom) are as follows: Sb-O 2.402(7); Sb-C 2.086(9), 2.086(10),
2.090(10), and 2.126(10). The bond angles are as follows: CaSbCe 97.04(4)d
egrees, 98.8(4)degrees, and 101.5(4)degrees; CaSbCa 176.4(3)degrees.
