K7B2P5O19: a novel alkali metal borophosphate with zero dimensional [B2P5O19]7− anionic units†
Abstract
A new anhydrous alkali metal borophosphate, K7B2P5O19, which exhibits a novel zero-dimensional [B2P5O19]7− anionic unit with internally connected P–O–P bonds, has been successfully synthesized and structurally characterized.
