A luminescent neutral cadmium(ii)–boron(iii)–imidazolate framework with sql net

One neutral boron–imidazolate-framework (BIF-35) based on the assembly of tetradentate B(im)4− ligands and (CdBr)+ units has been prepared, and it features a two-dimensional sql net. This work illustrates the feasibility of employing a wider variety of metal ions to fabricate new neutral BIFs.
