Title: Synthesis, crystal structure and magnetic property of a new cobalt(II) vanadate

A new cobalt(II) vanadate has been synthesized by hydrothermal reaction. It exhibits 3D cobalt(II) oxide architecture with Co{sub 12} member ring (MR) and Co{sub 6} MR tunnels along c-axis. V(2)O{sub 4} tetrahedra are located at the center of Co{sub 6}-MR tunnels whereas V(1)O{sub 4} tetrahedra and ‘isolated’ 1D Co(1)O{sub 6} octahedral chains are located at the Co{sub 12}-MR tunnels. The 3D cobalt(II) oxide architecture is constructed on irregular ladder chains formed by edge- and face-sharing of Co(2)O{sub 6} octahedra whereas the ‘isolated’ 1D Co(1)O{sub 6} octahedral chain in the tunnels are formed by face-sharing of Co(1)O{sub 6} octahedra. Magnetic property is investigated by means of magnetic susceptibility, magnetization and heat capacity measurement. Magnetic susceptibility and heat capacity measurement indicate a typical long-range spin-canting antiferromagnetic ordering below ~71 K; metamagnetic behavior was detected in the isothermal magnetization measurement at 2 K. - Graphical abstract: A cobalt(II) vanadate, Co{sub 7}V{sub 4}O{sub 16}(OH){sub 2}(H{sub 2}O) has been synthesized and structurally characterized. It exhibits antiferromagnetic interaction with weak spin-canting below ~71 K; metamagnetic behavior was detected in isothermal magnetization at 2 K. - Highlights: • Hydrothermal reaction of CoCl{sub 2}·6H{sub 2}O and Na{sub 3}VO{sub 4} yielded a new cobalt(||) vanadate. • It shows novelmore » structure since its large Co/V ratio. • It shows long-range spin-canting antiferromagnetic ordering below ~71 K. • Metamagnetic behavior was detected in the isothermal magnetization at 2 K.« less
