Abstract

We report the synthesis of two new low-dimensional oxides, LiVMO 5 (M=Mo, W), which contain S=½ transition-metal atoms, V IV :3d 1 and Mo V :4d 1 /W V :5d 1 , by topotactic reduction of the LiVMO 6 brannerites in hydrogen. LiVMO 5 crystallizes in orthorhombic structures related to the parent brannerite structure. The VMO 5 network of the new oxides is likely to correspond to one of the A 2 X 5 structures predicted by A. F. Wells (Philos. Trans. R. Soc. London A, 1984, 312, 589). LiVMoO 5 is metallic showing a charge density wave (CDW) instability around 230 K; interestingly, LiVWO 5 is a paramagnetic semiconductor down to 20 K.
