The present invention relates to a preparation method and the structure of complex palladium malonate adjacent filo crystal, the preparation method and the structure of a single-crystal compound in the meditation chemistry. In the conjugated [pd(mal)(phen)]question mark 2H₂O single crystal: pd represents palladium, mal malonic acid, phen 1,10-phenanthroline. The method takes advantage of malonic acid and the two ligants of 1, 10-phenanthroline assists the central iron palladium (II) coordination according to a certain volume ratio and a certain sequence so as to get target complex [pd(mal)(phen)]question mark 2H₂O. According to the method, malonic acid is firstly dissolved in to the water. Then metal ion palladium is added into the solution for reaction. After that, 1, 10-phenanthroline is added. The quantity ratio of malonic acid, metal ion palladium and 1, 10-phenanthroline is 2: 1: 1. The components and molecule structure of the prepared complex by the present invention is clear and definite. The present invention is of potential drug application value.
