Two stacked 2Dchiral/2Dchiral → 2Dachiral sheets based on V-shaped imidazolyl ligand and flexible aliphatic acids

Two new stacked 2Dchiral/2Dchiral → 2Dachiral coordination polymers {[Cd(BIDPE)(pim)]·(H2O)}n (1) and {[Cd(BIDPE)(glu)]·(H2O)}n (2) were prepared under hydrothermal conditions based on V-shaped ligand 4,4′-bis(imidazol-1-yl)diphenyl ether (BIDPE) and flexible polycarboxylic acids. In addition, the solid-state photoluminescent spectra were measured at room temperature.
