The crystal structure of La 3 ReO 8 , prepared at 1425°C, is reported to be different from a previous result on a preparation at 900°C (B AUD et al., 1979). The high temperature modification crystallizes in the monoclinic space group P2 1 /m with a = 7.757(1), b = 7.777(1), c = 5.928(1) Å, γ = 111.1°, Z = 2. The structure was solved by Patterson and Fourier methods from single crystal diffractometer data and refined to final R(F) = 0,073. The structure consists of isolated, distorted ReO 6 octahedra and double chains of edge‐shared La 4 O tetrahedra.
