Novel triply hydrogen bonded suprastructures based on [M-(tdpd) 2(L)2]2- (H2tdpd= 1,4,5,6-tetrahydro-5,6-dioxo-2,3-pyrazinedicarbonitrile, L = solvent) and melamine-analogous cations have been synthesized and characterized. The use of anions containing two AAA sets from [M-(tdpd)2(L)2] 2 together with cations containing one ODD set (A = hydrogen-bond acceptor, D = hydrogen-bond donor) leads to the formation of complementary triply hydrogen bonded modules in the solid state. In all cases, the building module is further extended via additional hydrogen-bonding in teractions to produce a tape, and tapes are assembled into sheets. These results show that a hydrogen-bonded module consisting of different kinds of building blocks, one of which is a metal complex that includes hydrogen-bond acceptor sites and the other is a hydrogen-bond donor molecule, will be attractive for constructing metal-containing supramolecular systems by the self-assembly technique.
