Hydrogen-bonded boron imidazolate frameworks

The research on tetrahedral imidazolate frameworks takes on a new direction into the supramolecular area through the synthesis of three hydrogen-bonded boron imidazolate (B[im](4)(-)) frameworks (HBIFs) that show distinct three- and two-dimensional supramolecular architectures: (1) the ionic diamond net containing the first reported Li+ complex with ethylene glycol, (2) four-connected double-layers built from a new neutral Li(tea)B(im)(4) (tea = triethanolamine) complex, and (3) three- connected (6,3) layer of H3O center dot BH(eim)(3).
