Synthesis and Structure of Tri-m-tolylantimony Bis (1- adamantanecarboxylate)

摘要

Tri(m-tolyl)antimony bis(l-adamantanecarboxylate) (3-MeC_6H_4)_3Sb[OC(O)C_(10)H_(15)]_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) A;the Sb-C distances are 2.103(5), 2.103(5), and 2.121(7) A;intramolecular Sb...O(=C) contacts are 3.069(5) A.
