- Isolation, Characterization, and Kinetics of Formation of the cis and trans Isomers of Bis(acetonitrile)dichloroplatinum(II)
-
The bis(acetonitrile)dichloroplatinum(II) obtained by the standard procedure has been shown to be a mixture of the cis and trans isomers the composition of which depends upon the experimental conditions used.The pure isomers have been characterized by i.r

- Platinum(II) complexes of substituted pyridine and pyrazole derivatives
-
A series of new platinum(II) halo complexes of substituted pyridines and pyrazoles: [trans-PtCl2(C7H7N)2], [trans-PtCl2(C3H4N2)2], [trans-PtCl2(C6H7N)2] and [trans-PtCl2(C4H6N2)2] has been synthesized, and the complexes have been characterised on the basis of their IR, 1H NMR, UV/vis and elemental analysis data. Trans-dichloroplatinum(II) complexes of nitrogen cyclic compounds have been prepared through the reaction of K2[PtCl4] with the corresponding ligands in water or a mixture of water and an organic solvent. The coordination reaction of 3- or 4-substituted pyridine is complete within 10 h and the yields are more than 60%, but that of 2-substituted pyridine requires a longer time (15 h) and the yields are low (44%). Platinum complexes of pyridine with a vinyl group at the ortho position could not be obtained, but those with a methyl or a vinyl group at the para position have been obtained. Each complex has a trans square-planar structure, the platinum being coordinated by two halogen and two nitrogen atoms and lying at a centre of symmetry.
