✦ Synopsis

Complexes of the ligands Ph2P(CH&PPh, (n = 8, 10, or 16) with cobalt(II), nickel(II), rhodium(I) and iridium(I), and of EtS(CH&SEt with palladium(I1) and platinum(I1) Experimental Spectroscopic data were obtained with the following spectrometers: infrared, Perkin-Elmer 621 and Beckman IR72; electronic, Beckman Acta IV; 'H NMR, Perkin-Elmer-Hitachi R20, Perkin-Elmer R32; 3'P NMR Bruker WP80; mass, AEI MS902. Molecular weights 'were determined in chloroform on a Beckman-Hitachi osmometer. Magnetic moments were measured by the Faraday method by Mr. S. Chapman, to whom we are grateful. The ligands were prepared by standard methods [2, 31, and characterised by chemical analysis and mass spectrometry. The complexes were obtained by methods of which the following are typical.
