Configuration space: the molecules were systematically rotated within the unit cell (a = 26.1, b = 3.82, c = 24.0 Å, β = 94.0°, space group C2/c) around their symmetry axes (yaw, pitch and roll) in steps of 1° from −45 to +45°. Configurations with a total degree of overlap between neighboring molecules of less than 1.0 Å are shown as dark spots in this visualization of the resulting 91 × 91 × 91 matrix.
