报道了2，5-双(α-吡啶)吡咯酸酯的钯和铂金属配合物，并用光谱分析、单晶X射线衍射和元素分析对其进行了表征。这些配合物的单晶X射线结构显示出明显的π反键的结构特征。为了说明这种影响，将键长与未金属化的PDP和以前报道的没有回键的锌(II)络合物进行了统计比较。密度泛函理论计算被用来帮助理解观察到的现象的电子结构基础。
Palladium and platinum metal complexes of 2,5-bis(α-pyridyl)pyrrolate (PDP) are reported and characterized by spectroscopic methods, single-crystal X-ray diffraction, and elemental analysis. The single-crystal X-ray structures of these complexes exhibit structural features indicative of significant π-backbonding. To illustrate the effect, bond lengths are statistically compared to unmetalated PDP and to a previously reported Zn(II) complex that exhibits no backbonding. Density functional theory calculations are used to aid understanding of the electronic structural basis of the observed phenomena.
