N2 - Phosphorus-31 NMR and X-ray crystallography show that the two similar chelating triphosphine ligands PhP(CH2CH2PPh2)2(2,2-P3) and PhP(CH2CH2CH2 PPh2)2(33-P3) form cobalt(I) complexes having trigonal-bipyramidal and square-pyramidal structures, respectively. The structures and PP coupling constants of [Co(33-P3)(P(OMe)3)CO]BF4·1THF and [Co(22-P3)(P(OMe)3)2]BF4 are given, and the change from square-pyramidal geometry in [Co(33-P3)P(OMe)3)CO]+ to trigonal-bipyramidal in [Co(22-P3)(P(OMe)3)2]+ may be rationalized in terms of a decreased "chelate bite angle" for the PhP(CH2CH2PPh2)2 ligand.
