A novel magnesoborate, Mg-7@[B69O108(OH)(18)], with a 3D supra-molecular framework has been made under solvothermal conditions, and features wonderful snowflake-like channels assembled from unprecedented [B69O108(OH)(18)] clusters. Notably, unique triple-helical ribbons reside in the middle of the B-69 cluster. Up to now, the discovery of a B-69 cluster sets a new record in cluster sizes among borates.
