Abstract

Complexes of the nucleic bases adenine (ade), guanine (guaH), cytosine (cyt), 2-thio-cytosine (thio-cyt), and the nucleosides adenosine (ado), guanosine (guoH), and inosine (inoH) with ruthenium trichloride have been prepared and characterized by infrared spectroscopy, diffuse reflectance spectra, conductivity, and magnetochemical measurements. On comparison of the infrared spectra of the prepared compounds with previous studies, suggestions are made about the binding site of the metal to the ligand. The complexes have normal magnetic moments close to the spin-only value. The electronic spectra confirms the octahedral structure of the complexes.

摘要

已制备了腺嘌呤（ade）、鸟嘌呤（guaH）、胞嘧啶（cyt）、2-硫代胞嘧啶（硫代-cyt）等核酸碱基以及腺苷（ado）、鸟苷（guoH）和肌苷（inoH）与三氯化钌的配合物，并通过红外光谱、漫反射光谱、电导率和磁化学测量对其进行了表征。通过将制备的化合物的红外光谱与先前的研究进行比较，对金属与配体的结合位点提出了建议。这些配合物具有接近仅自旋值的正常磁矩。电子光谱证实了配合物的八面体结构。
