The mol. structure of meso-tetrakis 3,4-bis(carboxymethyleneoxy)phenyl porphyrin (T3,4CPP) and the combination of Re = O with T3,4CPP are studied using the DFT(d. functional theory) with B3LYP method. Their optimum geometry structures, FMO and combination energy are calculated and analyzed. The porphin ring in T3,4CPP keeps good planarity and exactly similar geometry with sep. porphin ring. Also the combination energy of Re = O with T3,4CPP on porphin ring is remarkably higher than that of Re = O with T3,4CPP on carboxymethyleneoxy group of side chain. And stability of the former complex is much higher than that of the latter one. These imply that 188Re = O should be labeled with T3,4CPP on porphin ring while not on carboxymethyleneoxy group of side chain. It still shows that during combination of Re = O with T3,4CPP on porphin ring, electron shifts from carbon atoms to nitrogen atoms. It still shows that after combination of Re = O with T3,4CPP on porphin ring, the porphin ring deviates slightly (5.7 degree) from planarity to Re = O, and four nitrogen atoms slightly expand toward Re = O with the ring diameter deduced by 0.15-0.20 ?.
