Autostereographic projections (Katrusiak, 2001) of SeC(NH2)2 phases: (a) α at 0.1 MPa (c.f. Fig. S9); (b) β at 0.21 GPa; and (c) 3SeC(NH2)2·2H2O at 0.52 GPa. Hydrogen bonds NH⋯Se and OH⋯Se are indicated by blue dotted lines; the voids shown in grey in phase α were calculated by Mercury (Macrae et al., 2008) for the probe radius of 1.0 Å and grid step 0.1 Å (c.f. Fig. S10). |
