A nickel(Ⅱ) complex [Ni(La)2](NO3)2 (1) with bidentate racemic 1,2,2-trimethylcyclopentane-1,3-diamine ligand has been synthesized and characterized by IR, EA, ES-MS, and its X-ray diffraction study reveals that the nickel(Ⅱ) center is tetra-coordinated by one D- and one L- diamine ligands, and a three-dimensional hydrogen-bond-sustained network is formed in the solid state by means of the eight-membered N-H…O hydrogen bond cycle. This compound also supplies a good comparison to the chiral complex [Ni(Lb)2]Cl2·2H2O (2) (Lb=D-(+)-1,2,2-trimethylcyclopentane-1,3-diamine). CCDC: 218122. 相似文献

制备抗肿瘤药物庚铂的新方法 总被引:3,自引:2,他引:3
Sunpla (SKI2053R), an anti-tumor drug in clinic use, has been prepared by a new method in which mercurous ions instead of silver ones were used to remove the coordinating halide anions from the intermediate, [R(-NH2)2PtX2], and alkaline earth cations malonate or ammonium malonate were applied in the synthesis. The resulting platinum(Ⅱ) complex has been characterized with its IR, 1H-NMR and 13C-NMR, FAB-MS and TG-DTA spectra. 相似文献
