I.R. INVESTIGATIONS ON SOME HYDROGEN BONDED COMPLEXES OF PLATINUM(II) INVOLVING P-F LIGANDS

Abstract

I.R.-spectroscopic investigations of two hydrogen-bonded platinum(II) complexes involving arylphosphonofluoridous acids and their anions (1 and 2) are reported. The hydrogen bonds observed were found to differ significantly, depending on the substituents on the phenyl ring: whereas compound 1, involving unsubstituted phenyl rings, corresponds to Speakman's A type, the xylyl-substituted compound 2 is of type B in the Speakman terminology. All the characteristics of a hydrogen bond were found to disappear upon replacing hydrogen by a bridging BF₂ group.
