Structural transition between a (4,4)-net and a CdI2-net in Cd(II) compounds and conversion from a mixture to a pure substance

摘要

The coordination of a rigid triangular ligand 2,4,6-tris[4-(1H-imidazole-1-yl)phenyl]-1,3,5-triazine (TIPT) with Cd(II) ions afforded two compounds with structural motifs of a CdI2-type and a (4,4) network for anions OTf- (CF3SO3-) and OTs- (p-CH3C6H5SO3-), respectively, between which structural transition can be induced by anion exchange via solvent-mediated recrystallization process. Using this method, a pure substance can be obtained from a mixture under the excess of certain kind of anions. (C) 2015 Elsevier B.V. All rights reserved.
