Preparation and characterization of platinacycloalkanes containing nitrogen donor ligands

Abstract

Platinacycloalkanes of the type [PtX₂(CH₂)_n(NN)] and [PtCl₂(C₃H₅Me)(NN)] (where X = Cl, I; n = 3 or 4; NN = bis(1-pyrazolyl) methane, bis(3,5-dimethyl- l-pyrazolyl) methane, bis (2-pyridyl) methane and 2,2'-b ipyridyl) have

been prepared and characterized by elemental analyses, IR, ¹H and ¹³C NMR spectroscopy. The compounds [PtCl₂(C₃H₅Me)(NN)] exist as mixtures of 2- and 3- methyl platinacyclobutane isomers. In solution these compounds possess an octahedral geometry in which halo groups occupy the axial positions.
