Abstract
Pb6Re6O19 oxide has been synthesized in a sealed evacuted silica tube and by high-pressure high-temperature technique. Its crystal structure , refined from X-ray powder data (a = 9.3162(1) Angstrom, space group Pn3, R-I = 0.021, R-p = 0.067), is based on a three-dimensional networ k of Re2O10 groups linked together by corner sharing. The short Re-Re separation inside the Re2O10 groups (2.45 Angstrom) indicates the pres ence of a metal-metal bonding.
