Abstract:The mixed-ligand pentaborate, [Cu(C12N2H 8)2(C2H3O2)][B 5O6(OH)4]  C4H9NO (1), was synthesized and characterized by single-crystal X-ray diffraction, elemental analyses, powder X-ray diffraction, infrared spectroscopy, and thermogravimetric analysis. Two adjacent [B5O6(OH) 4]- polyborate anions are connected with each other by hydrogen bonds forming a novel zero-dimensional (0D) dimer {2[B 5O6(OH)4]-} which is further connected with [Cu(C12N2H8)2(C 2H3O2)]+ cations through hydrogen bonds to form a one-dimensional (1D) ribbon-like supramolecular structure with twenty-membered rings. The [Cu(C12N2H8) 2(C2H3O2)]+ cations are extended through  С        stacking interactions between the 1, 10-phenanthroline ligands forming a two-dimensional (2D) supramolecular network. The 1D supramolecular ribbons and the 2D supramolecular layers are further extended into a three-dimensional (3D) supramolecular framework through hydrogen-bonding interactions. Compound 1 is the first example of a borate where strong hydrogen bonds and  С        stacking interactions play important coordination roles in the formation of the 3D supramolecular framework.
