A novel aluminoborate open-framework [In(dien)2][Al2B7O16H2] with large chiral cavities templated by chiral main group metal complexes

Abstract

A novel aluminoborate open-framework [In(dien)₂][Al₂B₇O₁₆H₂] (1, dien = diethylenetriamine) with large chiral cavities has been constructed under solvothermal conditions, in which AlO₄ and chainlike B₄O₈ units are alternately linked to form a network with 20-membered ring windows and then further joined by XO₄ (X = 0.5 Al + 0.5 B) units to give a three-dimensional framework.
