Two mononuclear Tc complexes: [2,2′-(3-phenyl­propyl­imino)- and [2,2′-(propyl­imino)bis­(ethanethiol­ato)](4-methoxy­benzene­thiol­ato)­oxido­technate(V)

The mol­ecular structures of the two mononuclear title complexes, namely (4-methoxy­benzene­thiol­ato-κS)oxido[2,2′-(3-phenyl­propyl­imino)bis­(ethanethiol­ato)-κ³S,N,S′]technetium(V), [Tc(C₁₄H₂₁NS₂)(C₇H₇OS)O], (I), and (4-methoxy­benzene­thiol­ato-κS)oxido[2,2′-(propyl­imino)bis­(ethanethiol­ato)-κ³S,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.
