• resembles the quadruple hydrogen bond pattern found usually in copolymer and peptide structures. [28][29][30] The two tape structures alternate in a layer with C-H...O bonds from the methyl group connecting them. Interlayer contacts (see Figure 6b) are of the type, C-H...O and C-H...N (H(61B)...O(2), 2.324
