One-Pot Synthesis and Characterization of Three Chromotropic Supramolecular Isomeric Cu(II) Coordination Polymers as 1-D Zigzag or Helical Chains with Homochiral or Heterochiral Cu(II) Coordination Centres

•One-pot synthesis of three chromotropic supramolecular isomeric coordination polymers as 1-D zigzag or helical chains with homochiral or heterochiral Cu(II) coordination centres•The thermodynamic stability and the thermal stability of the three isomer increases in order of 1 < 2 < 3.•Linear correlations between the solid-state UV-Vis absorption maxima of the three isomers against the tetragonality (T) or the distortion percentage of the coordination geometry of Cu(II) from a perfect octahedral (Doct) were observed.
