Chiral induction in the ionothermal synthesis of a 3D chiral heterometallic metal-organic framework constructed from achiral 1,4-naphthalenedicarboxylate.

A chiral heteometallic compound, [(EMIM)NaCu(1,4-ndc)2]n (1), constructed from the achiral 1,4-naphthalenedicarboxylate (1,4-ndc) ligand has been ionothermally synthesized and structurally and magnetically characterized. The chiral induction effect of the enantiopure 1-ethyl-3-methylimidazolium (EMIM) L-lactate additive in the ionothermal reaction is briefly discussed.
