Assembly of robust two-dimensional sheet structures from crystalline ring-fused malonamidesvia cooperative hydrogen bonding of amide groups

Abstract

Ring-fused malonamides assemble into well-defined 2D-sheet structures based on the formation of 6 to 8 hydrogen bonds per molecule. The stacking manner and the interlayer distances of these sheets in the crystal can be manipulated by varying the size of the fused ring to form either interdigitated or segregated structures.
