Melamine (M) and succinimide (S) give cocrystals in a 1:1 ratio, in wh
ich a supramolecular network is formed by multiple hydrogen bonds. The
network is composed of two kinds of infinite links based on four mole
cular units, S-M-M-S; hydrogen bonds between the units to the a direct
ion, and the pi-pi stacks in the c direction.
