摘要

The reaction of tris(2,6-dimethoxyphenyl)bismuth with benzoyl peroxide in benzene affords tris(2,6-dimethoxyphenyl)bismuth dibenzoate Ar3Bi[OC(O)Ph]2, where Ar = 2,6-(MeO)2C6H3, which further reacts with AgNO3 and AgClO4 in chloroform to give Ar3Bi(NO3)2 and Ar3Bi(ClO4)2, respectively. The reduction of Ar3Bi[OC(O)Ph]2 with magnesium produces tris(2,6-dimethoxyphenyl)bismuth. The compounds were characterized by X-ray diffraction analysis, NMR and IR spectroscopy. The bismuth atoms in Ar3Bi[OC(O)Ph]2 (1) and Ar3Bi (3) have a distorted trigonal-bipyramidal coordination (C—Bi—C angles, 117.07(14)—125.49(14)°) and a trigonal-pyramidal coordination (C—Bi—C angles, 95.97(10)—100.90(12)°), respectively. The methoxy oxygen atoms are involved in non-covalent CMe—O⋯Bi interactions with the bismuth atoms (2.962(3)—3.290(3) Å (1), 2.994(2)—3.402(3) Å (3)).
