Supramolecular architectures constructed by strong hydrogen bonds. Crystal structures of novel one-dimensional polycatenane and three-dimensional interpenetrated network
We report novel supramolecular architectures based on flexible benzene-1,3,5-triacetic acid (bta) through strong hydrogen bonds. Partial deprotonated triacid forms a novel one-dimensional (1D) polycatenated chain (NH4)(15)[1,3,5-C6H3(CH2COOH)(15)(CH2COO)(15)] (1). While In the case of compound bta.H2O (2) with non-deprotonated triacid, a three-dimensional (3D) interpenetrated network was self-organized by strong O-H. .O hydrogen bonds. The conformation of flexible triacid is cis, cis, cis in 1 and cis, trans, trans in 2.
