A new phosphate, K{sub 2}(VO){sub 3}(HPO{sub 4}){sub 4}, has been synthesized hydrothermally and characterized by single-crystal x-ray diffraction, thermogravimetric analysis, and magnetic susceptibility. The title compound crystallizes in the monoclinic space group p2/c with a = 10.756(1), b = 9.147(3), c = 8.662(1) A{angstrom}, {beta} = 112.842(9){degree}, Z = 2, and R = 0.034. The structure is built from infinite chains of vertex-sharing vanadium oxide octahedra and HPO{sub 4} groups with the potassium cations located in sites within tunnels and cages in the structure. These infinite chains have alternating short and long V-O bonds. Each phosphate tetrahedron shares vertices with three octahedra, but two of these belong to the same infinite chain.
