Zinc(II)-boron(III)-imidazolate framework (ZBIF) with unusual pentagonal channels prepared from deep eutectic solvent.

The first zinc(II)-boron(III)-imidazolate porous material Zn(2)(im)Cl(2)[B(im)(4)] (ZBIF-1, im = imidazolate) integrating the structural features of two distinctly different imidazolate frameworks (i.e., ZIFs with the Zn-im linkage and BIFs with B(im)(4)(-) complex) has been realized by utilizing the unique chemistry of deep eutectic solvents.
