Self-assembled four-membered networks of trimesic acid forming organic channel structures

Abstract

By the co-crystallization of trimesic acid, TMA, with molecules such as dimethylamine, N,N,N',N' -tetramethylethylenediamine and methanol, it has been possible to generate hydrogen-bonded four-membered networks of TMA. The three-dimensional arrangement of the four-membered networks gives rise to channels occupied by the guest molecules. It has also been possible to generate a four-membered network by co-ordination of TMA with Co(II). (C) 2000 Elsevier Science B.V. All rights reserved.
