Reactions in the ZnO-VO{sub 2}-O{sub 2}O{sub 5} system afford the new phase Zn{sub 2}VO(PO{sub 4}){sub 2}, the structure of which was determined by the single-crystal X-ray diffraction method (I4cm, a = 8.9227(13), c = 9.039(3) {angstrom}, Z = 4, R = 0.026 for 228 unique reflections). The structure consists of infinite chains of corner-sharing VO{sub 6} octahedra along the c-axis and finite chains of edge-sharing ZnO{sub 5} and PO{sub 4} polyhedra parallel to the < 110 > directions. The VO{sub 6} octahedra are distorted such that alternately long and short V-O bonds along the axis of the infinite chain are formed. The Zn{sup 2+} ions exhibit a square pyramidal coordination.
