The invention relates to a novel metal organic framework molecular material of an electron-rich system. The molecular formula of the metal organic framework molecular material is C27H21CdN9O7, the chemical formula of the metal organic framework molecular material is [Cd(TIPA)(NO3)2].H2O, and the metal organic framework molecular material is called Cd-TIPA (TIPA=tris-(4-imidazolylphenyl) amine) forshort. The compound belongs to a monoclinic system and a C2 space group, and the topological structure is a utp type. The synthesis method specifically comprises the following steps: uniformly mixingCd(NO3)2.6H2O and TIPA in a mixed solvent of distilled water and N,N-dimethyl formamide, then transferring the mixture into a reaction kettle to react for 70-80 hours at 90-100 DEG C, cooling to a room temperature, separating out crystals, washing and drying to obtain Cd-TIPA. The novel metal organic framework molecular material can be used as a photocatalyst for catalytic reduction of heavy metal ions, in particular, Cr
