A novel supramolecular magnesoborate framework with snowflake-like channels built by unprecedented huge B69 cluster cages†
Abstract
A novel magnesoborate, Mg7@[B69O108(OH)18], with a 3D supramolecular 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 B69 cluster. Up to now, the discovery of a B69 cluster sets a new record in cluster sizes among borates.
