In order to deeply study the （SP-4-2）-[（1R, 2R）-1, 2-Cyclohexanediamine-N, N′]）bis（myristato-O） platinum（lI） （also known as miriplatin）, （1R, 2R）-（-）-1, 2-diamino cyclohexane and Potassium tetrachloroplatinate（II） were used as raw materia. We obtained the target compound miriplatin with the purity 〉 99.5%. In addition, we have characterized and analyzed the structure of the target compound miriplatin by infrared spectrum（IR）, High resolution mass speetrometry（HRMS）, Hydrogen Nuclear Magnetic Resonance （^1H NMR） and Carbon Nuclear Magnetic Resonance （^13C NMR）. Using Gaussian03 program package, the geometry of the target compound was optimized and calculated at the B3LYP/LANL2DZ basis set level. Stability analysis and vibration frequency analysis were also performed. By comparison of the experimental and calculated values, we confirm that the optimized molecular configuration and the experiment of molecular configuration were the same. According to the theory of QTAIM, the AIMALL program package was utilized to perform topology analysis of the chemical bonds of target molecule. The result gives a reasonable explanation to molecular configuration. Through this study, we have more in-depth understanding in cis-[double myristic acid （1R, 2R）-1, 2-diaminocyclohexane combined with platinum（II）], and provide theoretical basis to the study of related properties and also can be used to study other similar molecules.
