(57) [Summary] [Objective] A divalent platinum complex compound cis- [PtLL'I 2 ] with L ≠ L'that can realize high yield and avoid formation of isomers as much as possible. A manufacturing method is provided. [Structure] The compound is represented by the molecular formula cis- [PtLL'I 2 ], L ≠ L ', and (L) and (L') are ammine, a primary monoamine, a secondary monoamine, and a pyridine type amine. It was selected from among others. The molecular formula is [PtLI 2 ] x, and (x) Is an integer of 2 or more, and the compound (L ') is reacted with a compound selected from the group consisting of amine and dimethylformamide, and the reaction is carried out with water and another solvent in which the product is substantially insoluble. It is performed in a solvent selected from the group consisting of |
