The side-by-side type palladium(I) complex (2) was synthesized either by the reaction among , (dba=dibenzylideneacetone), and (benzylthiomethyl)diphenylphosphine (btmp) or by the reaction of (1) and .The structure of 2 was established by a single-crystal X-ray diffraction study; the crystals were monoclinic, space group P2₁/c, with a=13.537(3), b=19.550(3), c=17.240(4) Angstroem, β=114.59(2) deg, and Z=4; final R factor 0.049 for 5490 observed reflections.The structure showed that there is a metal-metal bond .Treatment of 2 with sodium iodide afforded the diiodo complex , whereas that with 4-methylpyridine (4-MePy) in the presence of AgClO4 gave 2.Moreover, 2 reacted with substituted acetylenes R=Ph, R'=H; R=CO2Me, R'=H; R=R'=CO2Me) to yield A-frame type complexes .All the complexes obtained in this study were characterized by means of elemental analysis, and IR and NMR spectroscopy.
