Basic beryllium acetate is insoluble in water but soluble in chloroform, consistent with it being nonpolar. It melts and sublimes in a vacuum without decomposition.[1]
Structure
"Basic acetates" consist of an ensemble of metal centres bound to a central oxide ion, and an collection of acetate ligands. Basic beryllium acetate has a tetrahedral Be4O6+ core with acetates (CH3CO2−) spanning each of the pairs of Be2+ centres.[2][3] It is diamondoid, consisting of interlocking six-membered Be2O3C rings. The structure is relevant to its considerable stability (the compound is distillable at 330 °C).
