Abstract

1H, 13C and 15N nuclear magnetic resonance studies of gold(III), palladium(II) and platinum(II) chloride complexes with phenylpyridines (PPY: 4-phenylpyridine, 4ppy; 3-phenylpyridine, 3ppy; and 2-phenylpyridine, 2ppy) having the general formulae [Au(PPY)Cl3], trans-/cis-[Pd(PPY)2Cl2] and trans-/cis-[Pt(PPY)2Cl2] were performed and the respective chemical shifts (delta1H, delta13C and delta15N) reported. 1H, 13C and 15N coordination shifts (i.e. differences between chemical shifts of the same atom in the complex and ligand molecules: Delta(coord)(1H) = delta(complex)(1H)-delta(ligand)(1H), Delta(coord)(13C) = delta(complex)(13C)-delta(ligand)(13C), Delta(coord)(15N) = delta(complex)(15N)-delta(ligand)(15N)) were discussed in relation to the type of the central atom (Au(III), Pd(II) and Pt(II)), geometry (trans-/cis-) and the position of a phenyl group in the pyridine ring system.

摘要

对通式为[Au(PPY)Cl3]、反式/顺式-[Pd(PPY)2Cl2]和反式/顺式-[Pt(PPY)2Cl2]的金(III)、钯(II)和铂(II)氯化物与苯基吡啶（PPY：4-苯基吡啶，4ppy；3-苯基吡啶，3ppy；2-苯基吡啶，2ppy）的配合物进行了1H、13C和15N核磁共振研究，并报告了各自的化学位移（δ1H、δ13C和δ15N）。讨论了1H、13C和15N配位位移（即配合物和配体分子中同一原子的化学位移之差：Δ(coord)(1H)=δ(complex)(1H)-δ(ligand)(1H)，Δ(coord)(13C)=δ(complex)(13C)-δ(ligand)(13C)，Δ(coord)(15N)=δ(complex)(15N)-δ(ligand)(15N)）与中心原子类型（Au(III)、Pd(II)和Pt(II)）、几何结构（反式/顺式）以及吡啶环系统中苯基位置的关系。
