- Organoamidometallics. II. Decarboxylation Syntheses and Structures of platinum(II) Complexes
-
The complexes (L = py, X = Cl or Br; L = 2-methylpyridine or 4-methylpyridine, X = Cl) have been prepared by decarboxylation reactions between PtX2(dmen) (dmen = N,N-dimethylethane-1,2-diamine) and thallous pentafluorobenzoate in the appropriate hot pyridine.Other organoamidoplatinum(II) complexes, (R = p-HC6F4, X = I; R = C6F5, X = Cl, Br or I; R = p-MeC6F4, X = Cl; R = p-ClC6F4 or p-BrC6F4, X = I) and (R = p-HC6F4; dmpy = 2,5-dimethylpyridine), have been prepared by analogous decarboxylations between PtX2(dmen), thallous 2,3,5,6-tetrafluorobenzoate, and the corresponding polyfluorobenzene, RF.The mixed halogen complex has been prepared similarly and the crystal structure determined.This shows square-planar stereochemistry with the halogen and pyridine trans to NC6F5 and NMe2 respectively.Comparison of spectroscopic data suggests the other complexes have similar stereochemistry.
