The compound Ph2PN(H)PPh2 (I) reacts under special conditions with M(CO)6 (M=Cr, Mo), Fe(NO)2(CO)2 and Co(NO)(CO)3 to give the new complexes cis-M(CO)22 (III, IV), 2NH (V), 2 (VI) and Co(NO)(CO)2Ph2PN(H)PPh2 (VII).Compound VI can also be prepared by reacting V with I.For III and IV proton NMR spectra indicate some interaction between o-protons of the phenyl rings and the cis-M(CO)2 groups.VI exists as an eight-membered ring complex without a metal-metal bond.On the basis of spectroscopic data VII seems to exist in two conformers.
