Figure 3
Motifs that arise from non-covalent interactions in 2,3-dimethylmaleic anhydride: (a) perpendicular C⋯O interactions (red and blue for C1=O2⋯C4ⁱⁱⁱ and C4=O3⋯C2ⁱ interactions respectively) and anti-parallel carbonyl interactions (black, representing C1=O2⋯C4^iv and C4=O3⋯C2^v, respectively), (b) weak C—H⋯O interactions (green) between sheets (weak C—H⋯O interactions within sheets have been omitted for clarity). Symmetry codes: (iii) −x + $[{1\over 2}]$ , y − $[{1\over 2}]$ , z; (iv) x + $[{1\over 2}]$ , y, −z + $[{3\over 2}]$ ; (v) x − $[{1\over 2}]$ , y, −z + $[{3\over 2}]$ . For other codes, see Table 4
