Charge assisted chiral hybrid H-bonded molecular networks

The co-crystallisation of [Fe(CN)5NO]2– and cyclic achiral 12+ and chiral 22+ or 32+ bisamidinium tectons leads in the crystalline phase to the formation of 1-D H-bonded achiral and chiral molecular networks respectively. In all cases, the network is formed by mutual bridging of the anionic and cationic units through a chelate mode of H-bonding.
