Lattice parameter and thermal expansion of ReO₃ between 291 and 464 K

The Bond technique was used to measure the lattice parameter of the red transition-metal oxide, ReO₃, as a function of temperature. At 298 K the lattice parameter is 3.7477 (1) Å. The thermal expansion is linear with temperature between 291 and 464 K and a linear coefficient of thermal expansion of 1.1 (1) × 10^-6 K^-1 was fit to the data.
