Abstract
Structural and chemical influences on interpenetration have been investigated through the preparation and structural analysis of a series of seven chiral coordination polymers using a phenylalanine-substituted naphthalenediimide ligand (H2PheNDI). The reaction of H2PheNDI with MnII or CdII and a range of linear dipyridyl-based coligands forms a series of coordination polymers which vary greatly in terms of their topologies and interpenetration while largely retaining a common metallomacrocyclic motif. The metallomacrocyclic motif is found in a tube-like 1D coordination polymer poly-[Cd(bipy)(OH2)(PheNDI)] (2) and a closely related 2D polythreaded network poly-{[Cd2(bipy)2(PheNDI)2][Cd(bipy)(DMF)1.5(NO3)2(OH2)0.5]} (3) which are synthesized as pure phases under slightly different conditions. The longer 1,2-di(4-pyridyl)ethylene (dpe) ligand gives rise to a 2D coordination polymer poly-[Cd4(DMF)(dpe)4(OH2)2(PheNDI)4] (5) in which the metallomacrocycles are connected only "sideways" rather than as a tube. This difference allows for 2-fold 2D → 2D interpenetration, between two crystallographically distinct sheets, whereby the dpe passes through the metallomacrocycle, assisted by face-to-face aromatic interactions. The use of a larger dipyridyl ligand, N,N′-bis(4-pyridyl)naphthalenediimide (4pyNDI), yielded 3D coordination polymers with distorted pcu topologies of the form poly-[M2(PheNDI)2(4PyNDI)2] (M = Cd, 6; Mn, 7) which contain neither the metallomacrocyclic motif nor interpenetration.
