Structural and 1H, 13C, 15N NMR spectroscopic studies of Pd(II) chloride organometallics with 2-phenylpyridine and ammonia, pyridine or its methyl derivatives
Pd(II) chloride organometallics with 2-phenylpyridine and pyridines of general formula [Pd(2ppy?)LCl] (2ppy? = C(2?)-deprotonated form of 2-phenylpyridine (2ppy), acting as N(1),C(2?)-chelating ligand; L = NH3, pyridine, 2-, 3-, 4-methylpyridine, 2,3-, 2,4-, 2,6-, 3,5-dimethylpyridine, 2,4,6-trimethylpyridine) were studied by 1H, 13C and 15N NMR. 1H, 13C and 15N NMR coordination shifts (i.e. differences of chemical shifts for the same atom in the complex and ligand molecules) were discussed in relation to the molecular structures. Single crystal X-ray structure of trans(N,N)-[Pd(2ppy?)(2,4,6col)Cl] was solved. The analysis of 15N NMR coordination shifts for the whole series of the studied organometallics exhibited that all of them had an analogous trans(N,N) geometry.
