【Abstract】 In this paper, syntheses and properties of solid tertiary coordination compounds of the title compound (1-2-4-acid, ANSH) with rare earths and o-phenanthro-line (Phen) were studied.The four coordination compounds obtained were confirmed as [RE(ANS)2· Phen] Cl·xH2O, for La and Nd, x= 1, for Eu, x = 2, for Ho, x = 5. Comparison of their IR spectra with that of ANSH, three conclusions can be drawn:1) intermolecular H-bond of ligand ANSH is ruptured accompanying formation of coordination compound, 2) proton dissociation of sulfonic acid group occurred,3) OH group probably participated in coordination.The characteristic 1H NMR shifts belonging to Phen shifted to high field in the coordination compounds. This shows the participation of N-atom in Phen in coordination with RE ion, which in turn decreases both the aromaticity of Phen and descreening action of π-electron cloud in benzene ring. The fluorescence spectra showed the decreasing of aromaticity of Phen after coordination. The thermogram shows the higher thermal stability of coordination compounds. Different 20 and I/I0 values in the X-ray diffraction pattern show the formation and the similarity of new coordination compounds. The coordination compounds obey activation type electric conduction pattern, so that they are a good class of semiconducting materials.更多还原
