| Summary: | 碩士 === 國立中正大學 === 化學暨生物化學研究所 === 99 === Seven novel coordination polymers and polyoxometalates containing organoarsonate (H3CPAA = (p-carboxyphenyl)arsonic acid) and/or 1,10-phenanthroline (phen) have been synthesized under hydrothermal reaction conditions : {[Cu(phen)2]2Mo6O18(HCPAA)2}•2H2O (1), {[Cu(phen)(H2O)3]2Mo6O18(HCPAA)2}•10H2O (2), [Cd(phen)(HCPAA)]•3H2O (3a), [Mn(phen)(HCPAA)(H2O)] (3b), [Cd(phen)(HCPAA)]•0.5H2O (4a), [Zn(phen)(HCPAA)] (4b), [Cd3(HCPAA)2(H2CPAA)2] (5). Compounds 1, 2, 3a, 3b,and 5 form 3D structures by π…π interactions and hydrogen bonds. The compounds 1 and 2 are shown to be 0D molecules. The structures of 3a and 3b contain two types of dinuclear clusters, four-member ring and eight-member ring, respectively. Compounds 4a and 4b exhibit 2D zigzag in which neighboring two metal centers are bridged by one HCPAA2-, and the structure of 5 features 2D structures by two different binding modes of H3CPAA.
