Abstract This paper firstly with o-phenylenediamine and 2-chloronicotinic acid and poly phosphoric acid (PPA) prepared BMOP, then BMOP and 2, 6 naphthalene dicarboxylic acid water ligands and four water cadmium nitrate and zinc nitrate by solvent thermal method in DMF and water mixed solution, temperature of 120 DEG C, bake for 3 days, obtained target product MOF-Cd and MOF-Zn。The two complexes by CCD detector for us then we prepared for crystal structure determination。At room temperature, we obtained the synthesized complexes of some physical properties, relative molecular mass, cell volume, Z value, s value, R value of unit cell parameters, and lists the synthesized complexes main bond lengths and bond angles。 In addition, through the experimental data, we draw the coordination environment map, the weak interaction diagram, the topological graph and the packing graph。 Experimental results show that MOF-Cd crystallize in the monoclinic crystal system, P21/c space group, the unit cell parameters are a =7。986 (3) Å, B = 11。937 (5) Å, C =14。863 (6) Å, alpha = 90。00 degrees, beta = 91。219 (4) ~, gamma = 90。00 degrees, v = 1416。6 (10) Å3; MOF-Zn crystallization in by crystal system, belong to I41 / a space group and the unit cell parameters are a =21。085 (3) a, B = 21。085Å and C =15。287 (4) Å, alpha = 90。00 degrees of beta = 90。00°, gamma = 90。00°, V= 6769 (3)Å3 。 MOF-Cd and MOF-Zn of the two compounds all have fluorescence, and the hair is blue。 Fluorescence is affected by ligand BMOP。
