摘要

Butterfly shaped dinuclear clusters 1-3, with phathaly-based dicarboxylatic group and CH2 spacer, are synthesized by the reaction of Ln(NO3)(3) (Ln = Eu3+, Nd3+, Pr3+) with ligand (2-({2-[2-carbosybenzoy])oxy]-ethoxy}carbonyal)benzoic acid) (H2L) in CH3CH2OH, CH3OH, (C2H5)(3)N and C2H3N. Their formula is identified as [Ln(2)(mu(2)-eta(3)-L)(2)center dot(CH3OH)(4)center dot(eta(2)-NO3)(2)]center dot 2CH(3)OH (Ln = Eu(1); Nd(2); Pr(3). The structures of the complexes are characterized by IR spectra, thermal gravimetry (TG), single crystal X-ray diffraction analysis as well as powder X-ray diffraction (PXRD). Structural analyses reveal that they are isomorphous. The thermal behaviors of complexes 1-3 were investigated and the complexes were found to be stable up to about 300 degrees C. Complex 1 exhibited luminescence emission bands at 590, 613, 685 and 697 nm at room temperature when excited at 395 nm. (C) 2017 Elsevier B.V. All rights reserved.
