A 3D chiral Zn(II) coordination polymer with triple Zn-oba-Zn helical chains (oba = 4,4'-oxybis(benzoate)).
The solvothermal reaction of Zn(II) and 4,4'-oxybis(benzoic acid) in the presence of anhydrous ethanol leads to the generation of a novel 3D chiral coordination polymer with triple helical chains; the resulting crystals were not a racemic mixture but had an enantiomeric excess, which was confirmed by measuring the optical rotation of bulk samples using solid state vibrational circular dichroism (VCD).
