Electronic Structure of Strongly Correlated Systems

Figure 21

The low-temperature crystal structure of T i 4 O 7 . Chains of four Ti sites run parallel to the pseudorutile 𝑐 -axis. Red and blue (light and dark on the black and white image) chains of four Ti atoms correspond to the (a) and (b) chains of Ti atoms, respectively. Further gradation of red and blue on light and dark subsets indicates inequivalent Ti sites in (a) and (b) chains.
