Abstract:Three new architectures based on Anderson-type polyoxometalates, (3-H(2)pya)[(3-Hpya)(2)Ag][AgAlMo6-H6O24].3H(2)O 1, HNa2[(3-pya)(3-Hpya)Ag] (2)[AlMo6H6O24] .8H(2)O 2 and [(3-Hpya)(2)Ag][(H2O)(2)Ag](2)[AlMo6H6O24].2H(2)O 3 (3-Hpya = 3-(3-pyridyl) acrylic acid), have been synthesized at the different pH values and characterized by elemental analysis, IR spectroscopy, TG analysis, powder X-ray diffraction and single crystal X-ray diffraction. Compound 1 was obtained at lower pH value (2.50), and represents a 3D hostguest compound containing the Ag-3-Hpya coordination complex guest and the 3D [AgAlMo6H6O24](2)-host. The host framework exhibits a 4-connected diamond topology, and is constructed from [AlMo6H6O24]3-clusters connected by Ag+ cations. When the pH value was increased slightly, compound 2 was obtained with a 1D chain structure built up of Anderson polyoxoanions, Ag-3-Hpya coordination complexes and binuclear sodium clusters. By further increasing the pH value (3.50), compound 3 was isolated as a 2D network in which [AlMo6H6O24]3-clusters are linked together by Ag+ cations and Ag-3Hpya coordination complexes. Their structural differences reveal that the pH value of the reaction system is the key factor influencing the structure and topology of three compounds. The UV-visible-NIR diffuse reflectivity spectra of 1-3 show that they can be regarded as a wide gap semiconductor. Furthermore, the pyrolysis of 1-3 produces three nanocomposites 1'-3' composed of silver microparticles dispersed in the metal oxides. The photocatalytic properties of 1'-3' have been investigated.
In 2002, Prof. Haiyan An received the B.S. degree in chemistry Northeast Normal University, Changchun, China; the M.S. in 2004 and the Ph.D. degree in 2007 in Key Laboratory of Polyoxometalates (POMs) Science of Ministry of Education. There were 30 papers published in Angew. Chem. Int. Ed., Inorg. Chem., Cryst. Growth Des., etc. during the degree. In 2006, she was awarded the Excellent Doctoral Dissertations Fund of Northeast Normal University. In July 2007, Prof. An joined College of Chemistry, Dalian University of Technology in the field of POMs. Her research interests are mainly focuse on the design, synthesis and properties’research of POM-based functional complexes with catalytic and drug activity. She has Undertaked two National Natural Science Foundation of China, one Specialized Research Fund for the Doctoral Program of Higher Education, one Natural Science foundation of Liaoning Province and one Scientific Research Foundation for Doctor of Liaoning Province. There are more than 30 SCI papers have been officially published in foreign periodicals during the work period, more than 20 of which list her as the first author and corresponding author.
