The asymmetric unit of the title compound, [InNa(C3H5O3)(4)] (n) , consists of one InIII ion, one NaI ion and four crystallographically independent l-lactate monoanions. The coordination of the InIII ion is composed of five carboxylate O and two hydroxy O atoms in a distorted pentagonal-bipyramidal coordination geometry. The NaI ion is six-coordinated by four carboxylate O atoms and two hydroxy O atoms from four l-lactate ligands in a distorted octahedral geometry. Each InIII ion is coordinated by four surrounding l-lactate ligands to form an [In(l-lactate)(4)]- unit, which is further linked by NaI ions through Na-O bonds to give a two-dimensional layered structure. Hydrogen bonds between the hydroxy groups and carboxylate O atoms are observed between neighbouring layers.
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.
