Article abstract of DOI:10.1246/bcsj.54.2672

Bis(cyclohexyl isocyanide)palladium(II) chloride, PdCl2(C6H11NC)2 (1) was prepared from PdCl2.The configuration of the complex 1 is cis with respect to the isocyanides.The isocyano group in one cyclohexyl isocyanide takes axial conformation to chair form cyclohexyl group, while another takes equatorial conformation.By recrystallization of 1 from benzene bis(cyclohexyl isocyanide)palladium(II) chloride-benzene, PdCl2(C6H11NC)2(C6H6)2 (2) was prepared.IR spectrum of 2 shows a characteristics absorption at 700 cm^-1 which is due to the benzene incorporated in the complex.Similar benzene complex was also prepared from PdBr2.
