A process for the preparation of cis-platinum (II) complexes of 1,2-cyclohexanediamine isomers not contaminated with any dihydroxoplatinum (IV) complex. Specifically, a process for preparing cis-platinum (II) complexes of 1,2-cyclohexanediamine isomers represented by general formula (I) from potassium chloroplatinate and trans-(-)-1,2-cyclohexanediamine as the raw materials, wherein the water used in the steps of preparing the platinum compounds from the raw materials is a deoxygenated one and the preparation is conducted in a low-oxygen-concentration atmosphere to inhibit the deoxygenated water from being deteriorated by the absorption of oxygen and to inhibit the platinum compounds from being directly oxidized by atmospheric oxygen.
