Abstract

Abstract: The reproducible formation, in mild conditions, of three new 1D zigzag coordination polymers using sulfonylcalix[4]arene (TCASO2 ), metal M 2+ cations (M=Co or Zn) and rigid planar N‐shaped linkers (stilbene‐4, 4′‐dicarboxylic acid (1‐ 2H) or azobenzene‐4, 4′‐dicarboxylic acid (2‐ 2H)) is reported. The obtained coordination compounds (1‐TCASO2 Zn3, 1‐TCASO2 Co3 and 2‐TCASO2 Zn3 ) are characterized in the crystalline phase using single crystal and powder X‐ray diffraction (XRD and XRPD), TGA and IR‐spectroscopy. The three compounds present the same coordination pattern and 1‐TCASO2 Zn3 and 2‐TCASO2 Zn3 reveal to be isostructural. Due to a high porosity and amount of accommodated solvent molecules hosted in the network, the generated rigid 1D chains are capable to undergo a reversible dynamic solid‐state transformation in terms of crystal packing, accompanied with release/uptake of DMSO molecules leading to compression/stretching of the unit cell along one of the crystallographic axis which was attested by Rietveld refinement on XRPD data. Abstract : New 1D zigzag coordination polymers were generated using sulfonylcalix[4]arene, metal M 2+ cations (M=Co or Zn) and rigid planar N‐shaped linkers (stilbene‐4, 4′‐dicarboxylic acid or azobenzene‐4, 4‐dicarboxylic acid). The flexibility of crystal packing allowed to observe dynamic reversible solid ‐state transformation upon the release/uptake of solvent DMSO molecules for one of the CPs.
