Figure 2
Schematic drawing of the diffraction pattern at T = 95 K exhibiting hexagonal to monoclinic sixfold twinning. (a) q2, q1 + q2 and q1 belong to the green (1), blue (2) and red (3) orthorhombic or monoclinic domains, respectively. (b) Monoclinic twin domains 4, and 5 and 6 are generated by applying twofold rotation a axes parallel to the twin domains 1, 2 and 3, respectively. The assignment of the q-vectors to the twin domains has been chosen consistent with International Tables for Crystallography, Vols. A and C (Arnold, 2006BB1; Janssen et al., 2006BB17). The reconstructed reciprocal layer hk2 is given as Fig. S1 in the supporting information.
