Abstract:Tri(m-tolyl)antimony bis(1-adamantanecarboxylate) (3-MeC6H4)3SbOC(O)C10H15]2 has been synthesized with a yield of 90.0% by the reaction of tri(m-tolyl)antimony with 1-adamantanecarboxylic acid in the presence of hydrogen peroxide in ether. According to X-ray diffraction analysis data, the antimony atom has a distorted trigonal-bipyramidal coordination with the axially positioned oxygen atoms of carboxyl groups. The axial OSbO angle is 173.1(2)°; the equatorial CSbC angles are 112.0(1)°, 112.0(1)°, and 136.0(3)°; the Sb-O distance is 2.109(3)Å; the Sb-C distances are 2.103(5), 2.103(5), and 2.121(7) Å; intramolecular Sb…O(=C) contacts are 3.069(5) Å.
