A novel compound 5-o-[1-(3-ethoxymethyl-4-phenyl-5-ethoxycarbonyl-6-methyl-3,4-dihydropyrimidin-2-one)butoxy]phenyl-10,15,20-triphenyl zinc porphyrin(C_(65)H_(56)N_6O_5Zn) was synthesized and characterized by NMR,FT-IR and MS. The compound crystallizes out from chloroform and methanol mixture solution,and its crystal structure was measured by single-crystal X-ray diffraction,monoclinic system,space group P2_1/c with a = 17.2741(6),b = 16.3797(6),c = 41.0919(16) ?,b = 93.810(3)°,V = 11601.0(7) ?~3,Z = 4,S = 1.021,F(000) = 5000,R = 0.0749 and wR = 0.1771. Additionally,it has been revealed by X-ray analysis that Zn of porphyrin is coordinated with carbonyl O of dihydropyrimidinone,thus the porphyrin and pyrimidinone rings are distorted by the Zn–O coordination bond.
