New quadridentate phosphine ligands, 1,1,10,10-tetraphenyl-4,7-diaza-1,10-diphosphadecane (pp-PNNP) and 2,11-dimethyl-5,8-diaza-2,11-diphosphadodecane (mm-PNNP), were prepared from (ClCH2CH2NHCH2-)2*2HCl and NaPR2 (R = C6H5, CH3) and purified through their Ni(II) complexes.Seven new cobalt(III) complexes containing the phosphine ligand were prepared: (n+) (X2 = (Cl)2, (NCS)2, C5H7O2(1-) (2,4-pentanedionate ion), and CO3(2-)).Four complexes of (1+) (X = Cl, NCS) afforded only a trans(X,X) isomer, and (2+) and (1+) complexes yielded a cisβ isomer.The geometrical structures were assigned on the basis of the NMR and visible-ultraviolet absorption spectra.
