Organometallic compounds of transition metals containing phosphine and perchloroaryl ligands I. Preparation and studies of compounds of the type [MX(C6Cl5)(PPh3)2] (M  Ni,Pd)

Several stable new compounds of transition metals with C₆Cl₅ as ligand, of the type MX(C₆Cl₅)(PPh₃)₂] (M  Pd and X  Cl, Br, I, NCS, NCO, N₃; M  Ni and X  NCS, NCO, N₃) are described. Their preparation in some cases required in situ reaction of MX₂(PPh₃)₂], Mg and C₆Cl₆. The action of gaseous HCl and Cl₂ on the solutions of these compounds has been examined. The IR spectra of the cyanato and thiocyanato complexes indicates coordination through the nitrogen atom.
