Abstract:Four new organic-inorganic hybrid compounds based on the polyoxoanion [Co2Mo10H4O38](6-), namely [Zn-2(H2O)(5)(4,4'-bipy)(3)]H-2[Co2Mo10H4O38]center dot 5H(2)O 1, [Zn-2(H2O)(2)(bpe)(3)]H-2[Co2Mo10H4O38] 2, [Zn(H2O)(4)(H(2)bpp)(2)] [Co2Mo10H4O38]center dot 2H(2)O 3 and [Zn-3(Trz)(6)(H2O)(6)][Co2Mo10O38H6]center dot 12H(2)O 4 (4,4'-bipyridine = 4,4'-bipy, 1,2-bis(4-pyridyl)ethane = bpe, 1,3-di(4-pyridyl)propane = bpp, 1,2,4-triazole = Trz), have been synthesized and characterized by elemental analysis, IR spectroscopy, TG analysis, solid diffuse reflective spectroscopy, powder X-ray diffraction and single crystal X-ray diffraction. Crystal analysis reveals that compound 1 exhibits a 1D staggered ladder-like chain constructed from [Co2Mo10H4O38](6-) and zinc-4,4'-bipy complexes. Compound 2 shows a 1D zig-zag polymeric chain by the linkage of zinc-bpe complexes and [Co2Mo10H4O38](6-). In compound 3, [Co2Mo10H4O38](6-) units are linked by zinc ions to form a 1D inorganic chain, protonated H(2)bpp molecules can be connected together by directional hydrogen-bonding interactions to construct a 3D supramolecular framework. Compound 4 consists of linear trinuclear zinc units bridging six Trz ligands and a [Co2Mo10H4O38](6-) unit as the counter anion, extensive hydrogen bonds exist in the clusters forming a 3D supramolecular framework. Compounds 1-2 represent the first extended organic-inorganic hybrid structures based on Evans-Showell-type POMs. These compounds act as heterogeneous Lewis acid catalysts not only for the cyanosilylation of different carbonyl compounds with trimethylsilyl cyanide but also for recovery and reuse without displaying any significant loss of activity.
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.
