A series of 4-substituted pyridines were combined with Re(CO)5Cl to prepare fac-tricarbonylchlorobis(ligand)rhenium(I) complexes. The Re(I) complexes were characterized by 1H and 13C NMR spectroscopy, FTIR spectroscopy, HRMS, and in the case of L = 4-(trifluoromethyl)pyridine, 4-bromopyridine, 4-picoline, and 4-methoxypyridine, single crystal X-ray diffraction studies. In the carbonyl region of the
将一系列的4-取代的吡啶与Re(CO)5 Cl结合以制备fac-三羰基氯双(配体)r(I)配合物。Re(I)配合物的特征在于1 H和13 C NMR光谱,FTIR光谱,HRMS,在L = 4-(三氟甲基)吡啶,4-溴吡啶,4-甲基吡啶和4-甲氧基吡啶的情况下,单个晶体X射线衍射研究。在这些配合物的FTIR光谱的羰基区域中,随着吡啶上的取代基变得更具吸电子性,观察到的三个延伸转移到更高的能量。

Three Re(I) complexes (3, 5, and 7) (Re(CO)(3)CI(L)(2)) and three new Pt(II) complexes (4, 6, and 8) ([Pt(P(Et)(3))(2)(L)(2)](OTf)(2)), where L = pyridine, 1 (4-Py-EDOT) or 2 (4-Py-bithiophene), were prepared and characterized. The solid-state structures of 4 and 5 were determined by X-ray crystallography. Electrochromic polymeric films of 2, 5, and 6 were prepared and characterized.
