Abstract
A series of novel lanthanide complexes with the general formula [Ln(3,4-DClBA)3phen]2 (Ln=Ho(1), Nd(2), Sm(3), Dy(4), Eu(5), Tb(6), Yb(7) and Er(8), 3,4-DClBA=3,4-dichlorobenzoate, phen=1,10-phenanthroline) were prepared at room temperature and characterized. The crystal structures of complexes 1–8 have been determined by single crystal X-ray diffraction. These complexes are isomorphous and lanthanide ions are all eight-coordinated to oxygen atoms and nitrogen atoms with distorted square-antiprism geometry. The thermal decomposition mechanism and TG-FTIR spectra of gaseous products of thermal decomposition processes for complexes 1–8 were acquired through TG/DSC-FTIR system. The heat capacities of complexes 1–8 were measured using DSC technology and fitted to a polynomial equation by the least-squares method. Complexes 3–6 display characteristic lanthanide emission bands in the visible region. Meanwhile, these complexes exhibit in good antimicrobial activity against Candida albicans, Escherichia coli, and Staphylococcus aureu.
