Secondary Bonding. Part 15. Influence of Lone Pairs on Co-ordination: Comparison of Diphenyl-Tin(IV) and -Tellurium(IV) Carboxylates and Dithiocarbamates

Seven complexes of general type Ph2MX2 with X = carboxylate or dithiocarbamate have been prepared and their molecular structures determined (M = Sn, X = O2CMe, O2CCH2Cl, or S2CNEt2; M = Te, X = O2CCCl3, S2CNEt2, S2CNEtPh, or S2CNPh2).All but one show unsymmetrical bidentate co-ordination by the carboxylate or dithiocarbamate ligands; the tellurium complexes show substantially greater differences between the longer and shorter M-O or M-S distances.The presence of the lone pair transforms the co-ordination geometry from approximately tetrahedral (M = Sn) to pseudo-trigonal bipyramidal (M = Te).Replacing carboxylates by dithiocarbamate has a modest effect when M = Te, but in the tin compound the sulfur ligand co-ordination is almost symmetrical.This contrasts with the unsymmetrical bonding in Me2Sn(S2CNEt2)2.

Synthesis and Characterisation of Diorganotellurium(IV) Bis(haloacetates)

A new diorganotellurium bis(haloacetates) of the type R2Te(OCOR')2 (R = C6H5, p-MeOC6H4, CH3; R' = CF3, CCl3, CHCl2 and CH2Cl) have been prepared and characterised.The IR spectral data of these haloacetates indicate that both the haloacetate groups are eq
