Hydrothermal synthesis and structure characterization of a new 3D vanadium hydrogen phosphite with 14-ring channels: (C{sub 5}N{sub 2}H{sub 14})[VO(H{sub 2}O)]{sub 3}(HPO{sub 3}){sub 4}.H{sub 2}O

A new 3D vanadium hydrogen phosphite (C{sub 5}N{sub 2}H{sub 14})[VO(H{sub 2}O)]{sub 3}(HPO{sub 3}){sub 4}.H{sub 2}O, has been prepared by hydrothermal reactions and characterized by single crystal X-ray diffraction, infrared spectroscopy, thermogravimetric analysis, and magnetic techniques. It crystallizes in the triclinic space group P-1 (no. 2) with a=6.258(1)A, b=9.696(2)A, c=19.384(4)A, {alpha}=76.124(3){sup o}, {beta}=83.726(4){sup o}, {gamma}=75.222(4){sup o}, Z=2. The structure is built up from sharing equatorial oxygen atoms of VO{sub 5}(H{sub 2}O) octahedra with HPO{sub 3} tetrahedra, which can be viewed as a (3,4) connected net. The framework is mainly constructed by two types of four-ring related chains. Intrachain and interchain hydrogen bonds play an important role on supporting the framework structure. The 14-ring tunnels in the structure are filled with 1-methypiperazinium and water molecules, which also contribute the hydrogen bonding with the vanadium phosphite framework.
