The preparation and characterization of the complexes trans-PtCl2 {2-(N=CHR)-3-CH3C5H3N}(AsEt3) and trans-PdCl2{2-(N=CHR)-3-CH3C5H 3N}(PEt3) (R = a substituted aryl group) are reported. The molecular structures of trans-PtCl2{2-(N= CH(mesityl))-3-methylpyridine}(AsEt3) and trans-PdCl2(2-amino-3-methylpyridine)(PEt3) have been determined by X-ray analysis. The former reveals a relatively short imine proton-platinum separation of 2.43 (8) ?, which is confirmed in solution by the observation of a proton-platinum coupling constant. Despite this spin-spin coupling and the proximity of the proton to the metal, this interaction is considered to be weak. Crystal data for the Pt complex are as follows: a = 8.177 (2) ?, b = 10.832 (1) ?, c = 14.370 (2) ?; α = 82.99 (2)°, β = 81.29 (2)°, γ = 89.41 (2)°; V = 1248.7 (8) ?3; space group = P1, Z = 2. Crystal data for the Pd complex are as follows: a = 13.866 (1) ?, b = 7.597 (1) ?, c = 16.555 (1) ?; β = 101.971°; V = 1705.96 (6) ?3; space group = Cc, Z = 4. 1H, 13C, and 31P NMR data are reported for the complexes.
