摘要

Two new copper borates, namely H_6[(μ_4-O)- Cu_4@B_(20)O_(32)(OH)_8]·25H_2O (1) and H_6[(μ_4-O)- Cu_4@B_(20)O_(32)(OH)_8]·34H_2O·8H_3BO_3 (2), with 3D supramolecular framework have been made under solvothermal conditions, which built by novel cubic supramolecular cages with mesoscale cavities via the H-bondings. Interestingly, the cage is assembled by [(μ_4-O)Cu_4@B_(20)O_(32)(OH)_8] ({Cu_4@B_(20)}) cluster units with different point-group symmetry. Owing to extra H_3BO_3 molecules participated in building the supramolecular framework, 2 has a larger cubic cage size and higher non-framework volume, leading to the cage size extended to mesoporous size set as a version of "1 plus".
