Figure 3
Compound [4: R = 3,4,5-(MeO)₃C₆H₂·0.5DMSO]. (a) A two-molecule-wide column of molecules, formed from C4—H4⋯O31, C5—H5⋯O31 and C441—H41C⋯O345 hydrogen bonds, (b) columns linked into undulating sheets by C31=O31⋯π(1) interactions and (c) a spiral of molecules, which creates a channel into which the disordered solvate molecules are held by a number of C—H⋯X (X = O, N or S) hydrogen bonds: the channel is generated from C431–H43B⋯π(3), C451—H51B⋯π(3) and C451—H51C⋯π(2) interactions and lies along the crystallographic twofold axis.
