Herein, we demonstrated that poly (ethylene oxide)(PEO), urea and thiourea can crystallize into novel ternary complex with the molar ratio of guest polymer and host small molecule as 3:2, and proved that the ternary complex behaves isomorphism phenomenon by varying the ratio between urea and thiourea for the first time.This observation gives a boost to prepare co-crystals of different small molecules that cannot be obtained by direct mixing without the aid of polymer chains.
