Synthesis and Characterization of Palladium and Platinum Complexes of N,N'-Bis[2'-(diphenylphosphino)phenyl]propane-1,3-diamine. Single-Crystal Structures of <TEX>$[Pd(Ph_2PC_6H_4NC_3H_6NC_6H_4PPh_2)]$</TEX> and <TEX>$[Pt(Ph_2PC_6H_4NH)(SEt_2)Cl]$</TEX>

Novel mononuclear metal complexes with the formula <TEX>$[M(Ph_2PC_6H_4NC_3H_6NC_6H_4PPh_2)]$</TEX> (M=Pd (1); M=Pt (2)) were obtained when N,N'-bis[2'-(diphenylphosphino)phenyl]propane-1,3-diamine, I was mixed with cisdichlorobis(diethylsulfide)palladium and platinum in the presence of NEt3. Two mononuclear metal compounds with the fomula [M(Ph2PC6H4NH)(SEt2)Cl] (M=Pd (3); M=Pt (4)) were synthesized from <TEX>$M(SEt_2)2Cl_2$</TEX> and N-(2'-diphenylphosphinophenyl)-4-amino-1,1,1,5,5, 5-hexafluoro-3-penten-2-one, II by the elimination reaction of hexafluoro pentenone. The X-ray single crystal structures of 1 and 4 are described. X-ray single crystal diffraction analyses reveal that compound 1 is a mononuclear palladium compound with P,N,N,P-coordination mode and 4 is a mononuclear platinum compound with P,N-coordination mode.
