Two chiral coordination polymers constructed from (1R,2R)-1,2-diaminocyclohexane derivative: Syntheses, structures and properties

•Two chiral Zn(II)/Ag(I) coordination polymers have been synthesized.•The ligand possesses two different coordination modes.•The nonlinear optical and photoluminescent properties of two compounds have been investigated.

Two chiral coordination polymers were synthesized by using a chiral ligand (1R,2R)-1,2-bis(4-(1,2,4-triazolyl))cyclohexane to assemble with Zn(II)/Ag(I) salts. The different coordination modes of the ligand result in two diverse structures, such as a 0D structure for 1 and a 1D chain for 2, respectively. The chiral nature of compounds 1 and 2 was confirmed by circular dichroism spectra (CD) and second harmonic generation (SHG) efficiency measurements. Furthermore, the photoluminescent properties of compounds 1 and 2 have been investigated in the solid state at ambient temperature.
