| 摘 要： | A new borate H2EG]B7O10（OH）3] （1） based on B14O20（OH）6]4- polyborate anions has been solvothermally synthesized in the presence of H2EG as a template （EG = ethylene glycol）. The structure was determined by single-crystal X-ray diffraction and further characterized by FFIR, elemental analysis and thermogravimetric analysis. Compound 1 crystallizes in the triclinic system, space group Pi, with a = 8.5095（4）, b = 8.8694（4）, c = 10.0756（4） A, a = 95.094（2）, β = 96.936（2）, γ = 116.844（2）°, V = 664.66（5） A3. The structure of 1 consists of B14O20（OH）6]4- moiety, which could be regarded as the largest isolated polyborate anion so far. The anions are interlinked via hydrogen bonding to form a 3D supramolecular network, whereas the diprotonated H2EG]2＋ are filled in the free space of inorganic borate network and interact with the inorganic framework by extensive hydrogen bonds. It is noteworthy that the EG acts not only as a solvent, but also as a template.

The structure was determined by single-crystal X-ray diffraction and further characterized by FTIR, elemental analysis and thermogravimetric analysis. Compound 1 crystallizes in the triclinic system, space group P1, with a = 8.5095(4), b = 8.8694(4), c = 10.0756(4) A, α =95.094(2), β = 96.936(2), γ = 116.844(2)°, V = 664.66(5) A3. The structure of 1 consists of B14O20(OH)6]4- moiety, which could be regarded as the largest isolated polyborate anion so far. The anions are interlinked via hydrogen bonding to form a 3D supramolecular network, whereas the diprotonated H2EG]2+ are filled in the free space of inorganic borate network and interact with the inorganic framework by extensive hydrogen bonds.
