摘要
Crystalline tetraphenylantimony and tetratolylantimony complexes with N,N-dialkyldithiocarbamate ligands [Sb(C6H5)(4)(S2CNR2)] (R = CH3, C2H5, and C3H7 and R-2 = (CH2)(6)) were synthesized by ligand exchange reactions and studied by C-13 and N-15 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 C, 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.
