Abstract
Novel triply hydrogen bonded suprastructures based on [M(tdpd)~2~(L)~2~]^2−^ (H~2~tdpd=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 DDD 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 interactions 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.
