New chiral coordination polymers constructed from well elaborated achiral and chiral ligands

Abstract

The elaboration of structurally related tetrazolate-based ligands from achiral to chiral led to the formation of two new chiral coordination polymers (CCPs). Compound 1 contains an infinite 1D zigzag Hg chain and a 1D helical water chain, its chirality is induced by the symmetry breaking of an achiral ligand while compound 2 is a 3D framework with a new 3-connected structural topology constructed from a homochiral ligand. The chiral natures of the two CCPs were both confirmed by circular dichroism (CD) spectra. The luminescent properties of compounds 1 and 2 were also investigated. Their strong luminescence suggest that both compounds may be excellent candidates as potential photoactive materials.
