We report a new dielectric phase change co-crystal [C4H4O4]center dot[C3H9N] 1, among which [C4H4O4] is fumaric acid and [C3H9N] is isopropylamine / IPA. Single-crystal X-ray measurements show space group of 1 belongs to monoclinic P2(1)/c space group, and a homogeneous phase change occurs. Hirshfeld surface analyses reveal that three interactions of H center dot center dot center dot H, H center dot center dot center dot O and H center dot center dot center dot C contribute more than 90 % to the total forces, and the forces of the three bonds are different at different phases. \
