Title: Synthesis, crystal structure and magnetic property of a new nickel selenite chloride: Ni{sub 5}(SeO{sub 3}){sub 4}Cl{sub 2}

The new nickel selenite chloride, Ni{sub 5}(SeO{sub 3}){sub 4}Cl{sub 2}, was obtained by high-temperature solid state reaction of NiCl{sub 2}, Ni{sub 2}O{sub 3} and SeO{sub 2} in a 1:2:4molar ratio at 700{sup o}C in an evacuated quartz tube. Its structure was established by single-crystal X-ray diffraction. Ni{sub 5}(SeO{sub 3}){sub 4}Cl{sub 2} crystallizes in the triclinic system, space group P-1 (No. 2) with cell parameters of a=8.076(2), b=9.288(2), c=9.376(2)A, {alpha}=101.97(3), {beta}=105.60(3), {gamma}=91.83(3){sup o} and Z=2. All nickel(II) ions in Ni{sub 5}(SeO{sub 3}){sub 4}Cl{sub 2} are octahedrally coordinated by selenite oxygens or/and chloride anions (([Ni(1)O{sub 5}Cl], [Ni(2)O{sub 4}Cl{sub 2}], [Ni(3)O{sub 5}Cl], [Ni(4)O{sub 6}] and [Ni(5)O{sub 4}Cl]). The structure of the title compound features a condensed three-dimensional (3D) network built by Ni(II) ions interconnected by SeO{sub 3}{sup 2-} anions as well as Cl{sup -} anions. Magnetic property measurements show strong antiferromagnetic interaction between nickel(II) ions.
