Synthesis and structure of 2,4,6-trinitrophenoxide tetraphenylantimony and μ-oxo bis[(2,4,6-trinitrophenoxy)triphenylantimony]

μ-Oxobis[(2,4,6-trinitrophenolate)triphenylantimony (I) is synthesized by the oxidative addition reaction of triphenylantimony and 2,4,6-trinitrophenol in ether, in the presence of 30% aqueous hydrogen peroxide solution. 2,4,6-Trinitrophenoxide tetraphenylantimony (II) were obtained by interaction of pentaphenylantimony with I or 2,4,6- trinitrophenol in toluene. X-ray diffraction analysis of I and II. In the molecular complex I antimony atoms has trigonal-bipyramidal coordination, with the bridging oxygen atom (Sb-O 1.956(3) and 1.965(3) Å), and oxygen atoms picrate groups in the axial positions (Sb-O 2.287 (4) and 2.268(3) Å).The crystal of complex II present cations [Ph4Sb]+ and picrate anions interconnected by weak С-H···О(Ar)-bonds (2.34, 2.44 Å).
