Abstract:By introducing the flexible ligands 3- or 4-pyridylacrylic acid into the Anderson-type polyoxometalate system, three new hybrid frameworks were obtained: [(3-Hpya)(2)Na][(3-Hpya)(2)Mn(H2O)(2)] [CrMo6H6O24]center dot 4H(2)O 1 (3-Hpya 3-(3-pyridyl)acrylic acid), alpha-(4-Hpya)(2){[(4-Hpya) (2)(H2O)(3)Mn](2)[(H2O)(4)Mn(CrMo6H6O24)(])}center dot 12H(2)O 2-alpha,beta-(4-Hpya)(2)[(4-Hpya)(2)(H2O)(4)Mn] [CrMo6H6O24]{[(4-Hpya)(H2O)(3)Mn](2)(CrMo6H6O24)}center dot 12H(2)O 2-beta, (4-Hpya = 3-(4-pyridyl)acrylic acid). All compounds have been characterized by elemental analysis, IR and UV-vis spectroscopy, TG analysis, and single crystal X-ray diffraction. Compound 1 is made up of [CrMo6H6O24](3-) polyoxoanions covalently linked by Mn-3-Hpya and Na-3-Hpya complexes to yield an unprecedented 2D network, which represents the first example of 2D hybrid assemblies based on Anderson-type polyoxometalates and manganese complexes, displaying the common 2D(4,4) topological net. When the 4-Hpya ligand was used, two polymorphic compounds 2-alpha and 2-beta were obtained. Polymorphism in 2-alpha and 2-beta arises from the different connectivity between polyoxoanions and manganese units. Compound 2-alpha is a bi-supporting structure composed of a dimeric cluster containing two Anderson polyoxoanions connected by a bridging manganese group, and two Mn-4-Hpya complexes. Compound 2-beta is built up of bi-supporting polyoxometalate clusters, isolated Anderson polyoxoanions and Mn-4-Hpya fragments to yield a 3D supramolecular channel framework. Magnetic susceptibility studies performed on 1 and 2 reveal weak antiferromagnetic coupling between the metal centers in each case.
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.
