reacting [nBu4][Re(O)Cl4] or [Re(O)Cl3(PPh3)2] with the tridentate H2PNX (X = O, S) ligands and different monothiols. The characterization of the complexes involved IR, 1H and 31P NMR spectroscopy and X-ray crystallographic analysis in the case of 1 and 2. Complexes [Re(O)(κ3-PNO)(SPh)] (1), and [Re(O)(κ3-PNS)(SPh)] (2), adopt a distorted square pyramidal geometry (δ = 3.0°, 1 and δ = 1.3° for 2), with the
