The hydrido complexes cis-2> (P₂ = Ph2PCH2CH2PPh2), HTa(CO)3P_m (P_m = P₃: PhP(CH2CH2PPh2)2, P₄: 2, PP₃: P(CH2CH2PPh2)3) have been obtained from the photo-chemically produced complexes m> by ion-exchange chromatography on silica gel.The anionic and neutral complexes have been characterized by IR and 31P and 1H NMR spectroscopy.The temperature-dependent 1H(hydride)-31P NMR coupling patterns are interpreted in terms os a hydride-capped octahedral structure with restricted migration of the H(-) ligand between the octahedral faces.
