of square planar complexes, Pd(CzTrR)Cl (7a–d) and Pd(CzTR)Cl (8a–d). The analogous platinum complexes are prepared by deprotonation of ligand carbazole nitrogen under nitrogen followed by reaction with Pt(COD)Cl2 to give Pt(CzTrR)Cl (9b, 9d) and Pt(CzTR)Cl (10b, 10d). The X-ray structure of several ligands (5b, 5c, 6c) and their metal complexes (8b, 8d, 9b) are reported. Complexes 7–10d were examined
摘要 几个咔唑双(三唑)(CzTr R)和咔唑双(四唑)(CzT R)配体的合成(分别为5a–d和6a–d,其中R = Me(a),i – Pr(b ),报道了Bz(c)和CH 2 -2,4,6-C 6 H 2 Me 3(d))。这些配体与PdCl 2在回流乙腈中的反应提供了完整的正方形平面络合物系列,即Pd(CzTr R)Cl(7a–d)和Pd(CzT R)Cl(8a–d)。通过在氮下使配体咔唑氮去质子化,然后与Pt(COD)Cl 2反应,得到Pt(CzTr R)Cl(9b,9d)和Pt(CzT R)Cl(10b,10d),制备类似的铂配合物。报道了几种配体(5b,5c,6c)及其金属配合物(8b,8d,9b)的X射线结构。通过循环伏安法和DFT计算检查了配合物7-10d,以了解其电子结构。同一配体的Pd和Pt配合物(CzTr:7d,9d;CzT:8d,10d)显示出非常相似的氧化电位,
