  摘要：

  Forty-one pi-acid complexes of the type cis-[Pt(bipyO2H)(A)X2]X and trans-[PtL(A)X2] (A = C2H4, CO; X = Cl, Br; L = pyridazine {pdz}, pyrazine N-oxide {pzO}, quinoline {quin}, quinoline N-oxide {quinO}, 2,2'-bipyridine {bipy}, 1,10-phenanthroline {phen}) and their deuterated L and C2D4 analogues have been characterised employing infrared and H-1 nmr spectroscopy. The employment of nu(12) (CH2 scissors approximately 1460 cm-1) of eta(2)-ethene as a diagnostic probe in distinguishing between 4- and 5-coordination is proposed, while the summed percentage decrease of v2 + v3 (vC = C/delta-CH2) may be used to distinguish between N- and O-coordination. The use of chemical shifts (H-1 nmr spectroscopy) is confirmed as a suitable means to distinguish between 4- and 5-coordination and is also shown to be suitable for distinction between N- and O-coordination in four coordinate Pt(II) eta-2-ethene complexes. In contradiction of previous reports, it is found that J(Pt-H) cannot be employed to determine the coordination number.
