Two novel In(III) complexes, [In(bna)(Hbna)]{sub n} (1) and [In{sub 2}(bna){sub 2}(mu{sub 2}-OH){sub 2}]{sub n}.4nH{sub 2}O (2) (H{sub 2}bna=2,2'-dihydroxy-1,1'-binaphthyl-3,3'-dicarboxylate acid), have been reported. Complex 1 adopts a 2D layer structure, where each layer composed from homochiral ligands is chiral while the ligands in two neighboring layers are enantiomer. Complex 2 is constructed by individual -In-O-In- chains, which are further connected by bna{sup 2-} into a 3D honeycomb framework. As a derivative of H{sub 2}bna ligand, dmbna (3) was recrystallized for structurally comparison with 1-2 (dmbna=dimethyl 2,2'-dihydroxy-1,1'-binaphthyl-3,3'-dicarboxylate). X-ray powder diffractions (XRD) and thermogravimetric analyses (TGA) for 1-2 show that they are highly thermally stable in the solid state. Complexes 1 and 2 exhibit the intense yellow luminescence at 573 nm and blue luminescence at 459 nm at room temperature, respectively. And an astonishing blue shift of 105 nm is observed for complex 1 when it is measured at 10 K. - Graphical abstract: Two indium(III)-bna compounds were solvothermally synthesized. 1 adopts an unprecedented 2D chiral layer. 2 is constructed by -In-O-In- chains, which are further connected by bna{sup 2-} into a 3D honeycomb framework.
