Synthesis, spectroscopic and structural aspects of triphenylantimony(V) complex with internally functionalized acetylferroceneoxime: Crystal and molecular structures of [C5H5FeC5H4C(CH3)double bond; length as m-dashNO]2SbPh3 and C5H5FeC5H4C(CH3)double bon

Triorganoantimony(V) complex (C5H5FeC5H4C(CH3)double bond; length as m-dashNO)2SbPh3 (1) has been prepared by the reaction of Ph3SbCl2 with acetylferroceneoxime C5H5FeC5H4C(CH3)double bond; length as m-dashNOH (2) in 1:2 molar ratio in anhydrous toluene. The complexes have been characterized by elemental analyses, IR and NMR (1H and 13C) spectroscopic studies, and biologic activity was measured. And crystal structures of 1, 2 were reported. The coordination geometry around the antimony atom in 1 was slightly distorted trigonal bipyramidal with the carbon atoms of the SbPh3 unit in equatorial positions and the two oxygen atoms of the oxime group occupying axial positions. The free oxime was clearly hydrogen bonded (H–N 2.10 Å/2.04 Å in 2) to essentially form a dimer.
