Abstract

A new sodium vanadyl(IV) orthophosphate NaV0P04 has been synthesized by solid-state and hydrothermal method and characterized by single-crystal X-ray diffraction and magnetic susceptibility. It crystallizes in the monoclinic space group P2₁/c with a = 6.524(1), b = 8.455(4), c = 7.119(1), β= 115.29(1)°, Z = 4, R = 0.027, and is structurally similar to the triclinic analog LiVOPO₄. The structure can be described as close-packed infinite chains of trans-corner-sharing VO₆ octahedra with the holes around each chain filled with Na and P atoms. These infinite chains have alternating short and long V —O bonds and are similar to those found in β -VOPO₄. The Na atom has six close oxygen neighbors at distances of 2.268 to 2.511 Å.
