Four novel transition metal complexes, [Zn2(Bpz*eaT)2(HBTC)2]·(CH3OH)3 (1), [Co(Bpz*eaT)(HBTC)]·(CH3CH2OH)0.5·(H2O)0.5 (2), [Zn(Bpz*eaT)(H2BTA)(pz*H)] (3) and [Cu4(Mpz*T-O2)4(BTA)(H2O)8]·4H2O (4) (Bpz*eaT, 2,4-bis(3,5-dimethyl-1H-pyrazol-1-yl)-6-diethylamino-1,3,5-triazine; Mpz*T-O2, 6-(3,5-dimethyl-1H-pyrazol-1-yl)-1,3,5-triazine-2,4(1H,3H)-dione; pz*H, 3,5-dimethyl-1H-pyrazole; H3BTC, benzene-1,3,5-tricarboxylic acid; and H4BTA, 1,2,4,5-benzenetetracarboxylic acid), were synthesized by the reaction of metal salts (ZnSO4·7H2O, CoCl2·6H2O or CuCl2·2H2O), pincer N-heterocyclic triazine derivatives and aromatic polycarboxylate ligands. All the complexes were characterized by elemental analysis, IR spectroscopy, UV-vis spectroscopy, thermal gravimetric analysis and single-crystal X-ray diffraction. Structural analysis reveals that complexes 1 and 2 are 2-D layers and complex 4 is a 3-D network structure with hydrogen bonding. In addition, the photocatalytic performances of complexes 1–4 were studied under UV irradiation at room temperature and their photocatalytic activity was also discussed. The result showed that complex 1 possessed higher photocatalytic activity. [ABSTRACT FROM AUTHOR] |
