摘要
The organoantimony peroxide (Ar2SbO)(4)(O-2)(2) (Ar = C6H3OMe-2, Br-5) was synthesized by the oxidation of Ar3Sb with hydrogen peroxide in the presence or acetoxime or acetophenone oxime in dioxane. The product crystallizes with various content of the solvent molecules in the crystal unit cell [1.5 (I) and 6 (II), respectively]. An X-ray diffraction analysis of the solvates was performed. Four antimony atoms in the peroxide are in the octahedral coordination, and are linked through bridging oxygen atoms and two peroxide groups. The distances Sb-C, Sb-O-bridge, Sb-O-peroxide, O-O and Sb...Sb are 2.117-2.122, 1.960-1.972, 2.193-2.235, 1.461, 1.465 and 3.223-3.237 in I, and 2.112, 2.119, 1.957, 1,966, 2.204, 2,246, 1,467, and 3.2439 in II.
