Figure 3
The pressure dependence of: (a) D⋯A and (b) H⋯A distances for N—H⋯O, N—H⋯N and C—H⋯O contacts in crystals of BZC polymorphs (I) (circles) and (IV) (triangles), shown in red, blue and green, respectively. The sums of van der Waals radii are shown with dotted lines in corresponding colours. Data for samples obtained from MeOH:EtOH:H2O 16:3:1 volume solution are marked with full symbols, while open symbols mark data collected using DMSO. The ORTEP symmetry codes (Farrugia, 2012BB19) are explained in Table S2. Data points at 0.1 MPa were calculated based on the previously reported structure, refcode QQQAXG04 (Chan et al., 2009BB13).
