Matching geometrical arrangements in the isostructural forms Stz-I and Spn-VI. (a) Stz-I: A- and B-type molecules, connected by an H2'∙∙∙A4 bond, which serves as the only link between the nov (A) and hcb (B) nets. (b) Spn-VI: A larger separation between A and B molecules results in the absence of an H2'∙∙∙A4 connection between the nov and hcb nets. Symmetry operation (i) 3/2 - x, 1/2 + y, 1/2 - z.
