摘要：

The electronic structures of the perovskite-type tungsten oxide (W-O) layers of the monophosphate tungsten bronzes (MPTB) were examined by performing tight-binding band calculations. Our study shows that all known MPTB phases have one- and two-dimensional metallic bands regardless of the difference in the thickness of their W-O layers and in their octahedral distortions. Concerning this dimensionality of the electronic properties, the bond valence sum analysis is found to give erroneous predictions. We examine the origin of this failure and also that of the remarkable similarity in the MPTB electronic structures. © 1990, American Chemical Society. All rights reserved.
