Noble metal coordination compound and preparation method thereof

The invention provides a noble metal coordination complex and a preparation method thereof, aims to prepare a coordination compound with potential medicinal values, and is characterized in that potassium chloropalladite or potassium chloroplatinite and 2,2'-bipyridine4,4'-dicarboxylic acid are mixed according to certain molar ratio and then react under hydrothermal conditions to obtain the coordination compound. The preparation method comprises the following steps: the mixrure of potassium chloropalladite (chloroplatinite), 2,2'-bipyridine4,4'-dicarboxylic acid and water is stirred for thirty minutes under the ambient temperature, then the mixture is transferred into a polytetrafluoroethylene inner container (with the volume of 25 to 50 mL) of a hydrothermal reaction kettle, the temperature is reduced to the ambient temperature, and a [PdLCl2]*H2O yellow rectangular ([PdLCl2]*H2O brownish red rectangular) crystal is obtained. The compound is definite in composition and molecular structure and has potential medicine application values.
