Abstract
Bis(μ3-2-oxybenzaldoximato-O,O′,N)-(μ2-oxo)-bis(5-bromo-2-methoxyphenyl)antimony, which crystallizes from toluene in the form of a solvate, has been synthesized by the reaction between tris(5-bromo-2-methoxyphenyl)antimony and 2-oxybenzaldoxime in the presence of hydrogen peroxide. According to X-ray diffraction data, the structurally equivalent antimony atoms in a binuclear complex molecule are linked via two tridentate bridging ligands and an oxygen atom and have a distorted octahedral coordination to the C2O3N surrounding The trans-angles of the octahedron are CSbO (168.7(1)°), CSbN (164.1(1)°), and OSbO (159.3(1)°), and the bond lengths are Sb-C (2.127(4), 2.159(3) A) and Sb-N (2.238(3) A). A molecule contains the three types of Sb-O distances with a bridging oxygen atom (1.950(1) A), the oxygen atoms of oxy groups (2.002(2) A), and the oxygen atoms of oxime groups (2.091(2) A). Sb⋯OCH3 intramolecular contacts (3.097, 3.290 A) also exist.
