| Abstract: | Crystalline tetraphenylantimony and tetratolylantimony complexes with N,N-dialkyldithiocarbamate ligands Sb(C6H5)4(S2CNR2)] (R = CH3, C2H5, and C3H7 and R2 = (CH2)6) were synthesized by ligand exchange reactions and studied by 13C and 15N CP/MAS NMR spectroscopy. X-ray diffraction analysis revealed that the complex Sb(n-CH3-C6H4)4{S2CN(C3H7)2}] exists as the single molecular form, while Sb(C6H5)4{S2CN(CH2)6}] exists as two molecular conformers. The 13C and 15N signals were assigned to the positions of the atoms in the isomeric structures Sb(C6H5)4{S2CN(CH2)6}] in terms of different degrees of double bonding in the formally single =N-C(S)S-bond. |
