摘 要：<正> Compounds of the formula [Ln（pd）3（py）2] where Ln=La～Yb and Y except Pm and Tin,Hpd （=2,4-pentanedione） and py （=pyridine） have been synthesised and characterised by physical and spectral studies.Pyridine is coordinated in all the compounds.The covalency parameters β,b1/2,δ and η indicate at least somecovalency in these compounds.The compounds have been checked for their use as NMR shift reagents usingcholesterol as substrate.Eight coordinate compounds increase their coordination number when added to thesubstrate.
