Novel magnetic CoII complexes: Synthesis and characterization

“…Organic aromatic acids of H 2 L 1 and H 2 L 2 were synthesized by previously reported methods [22]. The Cd II complexes were hydrothermally synthesized in poly(tetrafluoroethylene)-lined stainless steel containers under autogenous pressure [23]. Single-crystal structures were measured at 293 K on a Bruker Smart Apex CCD singlecrystal diffractometer with λ (Mo Kα) = 0.7107 Å and solved using the SHELXL-97 program [24][25][26].…”

Four ultraviolet light-emitting Cd II complexes were hydrothermally prepared and their single-crystal structures and luminescent properties were fully studied. It is found that the addition of 2,2′-bipyridine not only changes the single-crystal structures, but also the luminescence spectra. (4), where L 1 = 3,3′-(4-phenyl-4H-1,2,4-triazole-3,5-diyl)dibenzoate, L 2 = 3,3′-(4-(4-fluorophenyl)-4H-1,2,4triazole-3,5-diyl)dibenzoate, and bpy = 2,2′-bipyridine, were hydrothermally synthesized and characterized by single-crystal X-ray diffraction, powder scattering spectra, and infrared spectra. 1-4 possess excellent thermal stability with decomposition temperature of ca. 340°C. Their powder samples mainly give luminescent spectra at 350, 339, 351, and 339 nm, respectively, which should be attributed to the ligand-centered π* → π transfer transitions. Additionally, 1-4 have weak emission bands at 400-500 nm, which are tentatively attributed to the triplet ligand to ligand charge transfer transitions.

Three ultraviolet light-emitting organic acids of 3,3'-(4-phenyl-4H-1,2,4-triazole-3,5-diyl)dibenzoic acid (Tz-1), 4,4',4″-(4H-1,2,4-triazole-3,4,5-triyl)tribenzoic acid (Tz-2), and 4,4'-(4-(4'-carboxy-[1,1'-biphenyl]-4-yl)-4H-1,2,4-triazole-3,5-diyl)dibenzoic acid (Tz-3) were successfully synthesized and fully characterized by the (1)H NMR, the IR absorption spectra, and the X-ray single crystal diffraction. It was found that Tz-1, Tz-2, and Tz-3 could give out the ultraviolet photoluminescent spectra centered at 369 nm, 365 nm and 350 nm, respectively. The luminescence quantum yields of Tz-1 and Tz-2 were measured to be 0.20 and 0.14, respectively. Additionally, the density functional theory (DFT) and the time-dependent DFT calculations were also carried out for Tz-1, Tz-2, and Tz-3.
