PHENYLANTIMONY BIS(MONOTHIOACETATE) - ITS PREPARATION, STRUCTURE AND STABILITY Academic Article uri icon

abstract

  • Phenylantimony bis(monothioacetate) has been prepared and fully characterised by single crystal X-ray diffraction. The crystals are triclinic, P1, with a 10.761(4), b 7.304(3), c 9.608(7) , a 112.84(5), 102.57(5) and 100.17(5). The theioacetate groups bond primarily via sulphur (Sb-S 2.451, 2.471 ) but substantial Sb.O interactions lead to a bis-chelate structure. Isolated PhSb(SAc)2 molecules have distorted square-pyramidal geometry with an apical phenyl group but intermolecular Sb.S interactions (3.802 ) trans to the phenyl group give weak dimers in the solid state. Attempts to prepare Ph2SbSAc gave only mixtures of PhSb(SAc)2 and Ph3Sb; in the related acetate series, Ph2SbOAc is well-known, but PhSb(OAc)2 could not be prepared. Possible reasons for the instability of Ph2SbSAc and PhSb(OAc)2 are considered. 1986.
