| Summary: | 碩士 === 國立臺北科技大學 === 化學工程研究所 === 96 === Treatment of MNO3·nH2O (M = Eu, Tb, Sm, Er, Gd) with 4'-(4-methylphenyl)-2,2':6',2'-terpyridine (L) in acetonitrile under hydrothermal conditions led to the formation of metal complexes Eu2(L)2(C2O4) (1), Tb2(L)2(C2O4) (2), Er2(L)2(C2O4) (3),Gd2(L)2(C2O4) (4) and Sm2(L)2(C2O4) (5). These products are dimetallic compounds with an oxalato-bridging group. The crystal systems in these compounds are
monoclinic, with space groups of P21/c. It is noteworthy that the C-C bond length of the bridging oxalate is great than the normal bond length.
Treatment of Cu(NO3)2 and CoCl2 with 4'-(p-carboxyphenyl)-2,2':6',2'-terpyridine(p-CPTPy) yielded 1-D coordination polymers of Cu2(C22H15N4O5)2‧(H2O) (6) and
Co(C22H14N3O2)2‧H2O(7), respectively. Compounds 1-7 were characterized using elemental analysis, IR, thermal analysis and X-ray powder diffraction studies. The
molecular structures of products 1-7 were further confirmed by single -crystal X-ray diffraction analysis.
