Abstract:Six 3D architectures based on lanthanide-substituted polyoxometalosilicates, KLn[(H2O)(6)Ln](2)[(H2O)(4)-LnSiW(11)O(39)](2)center dot nH(2)O (Ln = La 1, n = 42; Ce 2, n = 40), H[(H2O)(6)Nd](2)[(H2O)(7)Nd][(H2O)(4)NdSiW11O39]-[(H2O)(3)NdSiW11O39]center dot 13H(2)O (3), H2K2[(Hpic)(H2O)(5)Ln](2)[(H2O)(4)LnSiW(11)O(39)](2)center dot nH(2)O (Ln = La 4, n = 18.5; Ce 5, n = 35; Nd 6, n = 36; Hpic = 4-picolinic acid), have been synthesized and characterized by elemental analysis, IR and UV-vis spectroscopy, TG analysis, powder X-ray diffraction and single crystal X-ray diffraction. Compounds 1 and 2 are isostructural, built up of lanthanide-substituted polyoxoanions [{(H2O)(4)Ln(SiW11O39)}(2)](10-) linked by Ln(3+) cations to form a 3D open framework with 1D channels. The polyoxoanion [{(H2O)(4)Ln(SiW11O39)}(2)](10-) consists of two alpha(1)-type mono-Ln-substituted Keggin anions. When Nd3+ ion was used instead of La3+ or Ce3+ ions, compound 3 with a different structure was obtained, containing two kinds of polyoxoanions [{(H2O)(4)Nd(SiW11O39)}(2)](10-) and [{(H2O)(3)Nd(SiW11O39)}(2)](10-) which are connected together by Nd3+ ions to yield a 3D framework. When 4-picolinic acid was added to the reaction system of 1-3, isostructural compounds 4-6 were obtained, constructed from the polyoxoanions [{(H2O)(4)Ln(SiW11O39)}(2)](10-) linked by picolinate-chelated lanthanide centers to form a 3D channel framework. From a topological viewpoint, the 3D nets of 1, 2, 4, 5 and 6 exhibit a (3,6)-connected rutile topology, whereas the 3D structure of 3 possesses a rare (3,3,6,10)-connected topology. The magnetic properties of 2, 3, 5 and 6 have been studied by measuring their magnetic susceptibilities in the temperature range 2-300 K.
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.
