Synthesis and Structure of -Oxobis[(nitrito)triphenylantimony]
摘要:
Triphenylantimony dibromide was reacted with sodium nitrite in aqueous acetone to obtain mu-oxobis[(nitrito)triphenylantimony]. According to single-crystal X-ray diffraction data, the Sb atoms in the molecule have a trigonal bipyramidal coordination. The molecule is centrosymmetric., the two Sb atoms are C linked with each other by a bridging oxygen atom [the SbOSb angle is 141.8(2)degrees, and the Sb...Sb distance is 3.7-154(5) Angstrom]. The Sb-O-br and Sb-O-term bond lengths are 1.9768(1) and 2.257(3) Angstrom, and the Sb...O and Sb...N distances are 3.020(4) and 3.070(6) Angstrom, respectively.
