Figure 5
Twin components of the α-NTO crystal structure. (a) and (b), (c) and (d), and (e) and (f) represent the structure rotated through 180° around the ao, bo, co axis. Molecules 1, 2, 3 and 4 are colored green, red, blue and yellow, respectively. Asterisks indicate ribbons with an inverted direction of propagation. Solid atoms represent the original structure and open atoms correspond to the respective twin component. Dot/dashed lines indicate potential twin boundaries. |
