Abstract
Refinement of the crystal structure of V at 360 and 470 K in the metallic rutile phase shows that both the vanadium and oxygen thermal displacements are larger than those found in rutile phases of Ti and Cr or monoclinic phases of V or . The vanadium-vanadium distance along the rutile axis is anomalously short when compared with neighboring rutile phases while the other nearest-neighbor metal-metal and metal-oxygen distances vary smoothly across the series. A comparison of Debye temperatures calculated from heat-capacity and x-ray data suggests the presence of low-lying vibrational modes in metallic V.
