  New hypercoordinated organoantimony(V) bromides. Synthesis and structural characterization

  摘要：

  The oxidative addition of bromine to [2-(Me2NCH2)C6H4]SbBr2 and [2-(Me2NCH2)C6H4]Ph2Sb resulted in the new hypercoordinated organoantimony(V) compounds [2-(Me2NCH2) C6H4]SbBr4 (1) and [2-(Me2NCH2)C6H4]Ph2SbBr2 (2), respectively. The new species were isolated as colourless solids and their solution behaviour was investigated by H-1 and C-13{H-1} NMR spectroscopy. Single-crystal X-ray diffraction studies evidenced strong N -> Sb intramolecular interactions in 1 and 2. While 2 has a monomeric structure, in the crystal of 1 the molecules are associated in polymeric chains by weak Br center dot center dot center dot H contacts. The ionic derivative [{2-(Me2NH+CH2)C6H4}Ph2SbBr2]Br-center dot CHCl3 (3 center dot CHCl3) was isolated as a hydrolysis product during our attempts to grow single-crystals of 2 from a n-hexane/CHCl3 mixture of solvents.
