摘要：

Green colored single crystals of a reduced sodium vanadium(III) monohydrogenphosphate, NaV(HPO4)(2), were grown using a one-step mild hydrothermal method. The in situ reduction of V5+ to V3+ was performed using copper acetate as the reducing agent. The title compound crystalizes in the monoclinic space group Cc and exhibits a three-dimensional crystal structure that consists of distorted VO6 octahedra connected to PO3(OH) tetrahedra that are further connected via Na cations. The compound exhibits simple paramagnetic behavior at high temperatures and a discontinuity near 5 K is likely due to the onset of magnetic coupling. The compound was also characterized by TGA, IR and UV-vis spectroscopies. (C) 2017 Elsevier Masson SAS. All rights reserved.
