    Abstract:
    The molecular structures of the two mononuclear title complexes, namely (4-methoxybenzenethiolato-kappaS)oxido[2,2'-(3-phenylpropylimino)bis(ethanethiolato)-kappa(3)S,N,S']technetium(V), [Tc(C14H21NS2)(C7H7OS)O], (I), and (4-methoxybenzenethiolato-kappaS)oxido[2,2'-(propylimino)bis(ethanethiolato)-kappa(3)S,N,S']technetium(V), [Tc(C7H15NS2)(C7H7OS)O], (II), exhibit the same coordination environment for the central Tc atoms. The atoms are five-coordinated (TcNOS3) with a square-pyramidal geometry comprising a tridentate 2,2'-(3-phenylpropylimino)bis(ethanethiolate) or 2,2'-(propylimino)bis(ethanethiolate) ligand, a 4-methoxybenzenethiolate ligand and an additional oxide O atom. Intermolecular C-H...O and C-H...S hydrogen bonds between the monomeric units result in two-dimensional layers with a parallel arrangement.
