respectively. The complexes were characterized by elemental analysis and NMR (1H and 77Se) spectroscopy. Complexes 4 and 5 were also characterized by mass spectrometry. Molecular structures of 4, 5, 9, 14 and 15 have been established by single crystal X-ray diffraction analysis. Complexes 4 and 9 are isomorphous and crystallize in the space group P21/c of the monoclinic system where the selenolato and halo ligands
