Polymeric coordination system of [Ag2(NO3)2L]n [L = 1,4-bis((cyclohexylthio)acetyl)piperazine] that exhibits supramolecular isomerism with 2D and 3D frameworks

Depending on the solvents used for crystallization, silver nitrate and the flexible dithioether-type ligand incorporating piperazine diamide [L: 1,4-bis((cyclohexylthio)acetyl)piperazine] readily formed two distinct types of 2D (1) and 3D (2) coordination polymers with identical formula [Ag2(NO3)2L]n. The preparation and structural characterisation of 1 and 2 are reported as an example for the supramolecular isomerism.
