Three solvent dependent structures of 2,6-diaminopurine in N,N′-dimethylforamide (DAP-1-DMF), water (DAP-2-H2O), and methoxybenzene (DAP-3-CH3OC6H5) have been structurally characterized. They exhibit different structures because of the different involvement of solvent molecules in the hydrogen bonded frameworks. The DAP molecules tend to be self-assembled with other DAP molecules through hydrogen bonding interactions. DAP has very similar hydrogen bonding interaction patterns to the established DAT group (2,4-diaminotriazinyl), underlying the potential of this new unit for the construction of porous hydrogen bonded organic frameworks.
