説明

The crystal and molecular structure of the title complex was determined by the single-crystal X-ray diffraction method. The crystallographic data are: monoclinic, space group P21c, a=19.164(6), b=19.020(9), c=18.649(7) Å, β=95.06(3)°, and Z=8 (16 metal atoms are in a unit cell). There are two crystallographically independent dimeric [SbBr(C6H5)3]2O molecules, which are almost in the same form. Each antimony atom is bonded with three phenyl carbon atoms equatorially and one bromine as well as one bridging oxygen atoms axially, being in a trigonal-bipyramidal geometry. The Sb–O–Sb′ angles are 170.2(7) and 176.6(8)°, while the Sb–O lengths are in the range of 1.931(13)—1.958(13) Å, which are shorter than the sum of their covalent radii of the atoms: 2.15 Å.
