The synthesis and structural characterization of some triorganothin(IV) complexes of 5-(4-chlorophenylazo)salicylic acid: Crystal and molecular structure of triphenyltin 5-(4-chlorophenylazo)salicylate center dot 0.5C(6)H(14)

Three new triorganotin(IV) complexes, the trimethyl, tributyl and triphenyl derivatives of 5-(4-chlorophenylazo)salicylic acid, have been synthesised and characterised by H-1, C-13, Sn-119 NMR, IR and elemental analysis and t he crystal structure of triphenyltin-5-(4-chlorophenylazo)salicylate is rep orted. The crystals are monoclinic, space group P2(1)/n with a = 9.566(1) A ngstrom, b = 14.550(2) Angstrom, c = 22.528(3) Angstrom, beta = 94.04(1), V = 3127.8(7) Angstrom(3), Z = 4 and D-calc = 1.42 Mg.m(-3). There is an enc apsulated molecule of hexane incorporated in the structure. This complex ad opts a monomeric distorted tetrahedral configuration with the ligand coordi nated via a carboxylate oxygen.
