Abstract:Six new hybrid compounds based on [Co2Mo10H4O38](6-) polyoxoanion, (4-H(2)pya)(6)CO2Mo10H4O38 center dot 10H(2)O 1 (4-Hpya =3-(4-pyridyl)acrylic acid) and (4-H(2)pya)(4)[M(H2O)(6)]-[Co2Mo10H4O38].5H(2)O (M = Co 2, Ni 3, Cu 4, Zn 5, Cd 6), were synthesized and characterized by elemental analysis, IR spectroscopy, TG analysis, solid diffuse reflective spectrum, powder X-ray diffraction, and single crystal X-ray diffraction. Compound 1 crystallizes in the centrosymmetric space group P-1, which is built up of protonated 4-H(2)pya molecules and isolated [Co2Mo10H4O38](6-) polyoxoanions. Isostructural compounds 2-6 crystallize in the chiral space group P1 by spontaneous resolution, as a conglomerate of two enantiomerically pure crystals, which were obtained by adding different metal cations to the reaction system of compound 1. The structures of 2-6 comprise chiral [Co2Mo10H4O38](6-) anions, cationic [M(H2O)(6)](2+) units, and protonated 4-H(2)pya ligands. The chiral [Co2Mo10H4O38](6-) polyoxoanions can be connected up together by directional hydrogen-bonding interactions among terminal oxygen atoms of anions, coordinated water molecules and organic ligands to construct a 3D supramolecular chiral framework in 2-6. The absolute configuration of 2-6 was determined from the Flack parameter by X-ray crystallography and solid state circular dichroism spectroscopy. As far as we know, compounds 2-6 represent the first examples of chiral inroganic-organic hybrid species based on Evans-Showell-type polyoxometalates. Furthermore, the second harmonic generation (SHG) activities for 2 and 4 were measured, showing an SHG efficiency of approximately 0.9 X KH2PO4.
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.
