Abstract
The crystal structure of two open-framework ionic salts, namely [Co(bpy)3]3[PTMTC]2·(7 + x)H 2O (1) and [Co(bpy)3][PTMTCH]·29.5H2O (2), formed by the supramolecular arrangement of a polycarboxylate perchlorinated triphenylmethyl radical and a [Co(bpy)3]2+ cation have been determined. The absence of interpenetration in both frameworks shows large solvent-filled nanochannels with different shapes and sizes. The dimensions of these channels are 11 × 23 and 7 × 12 Å in 1 and 2, respectively. Furthermore, since both building blocks have a paramagnetic character, salts 1 and 2 present magnetic properties reflected by the presence of weak antiferromagnetic interactions.
