Basic beryllium formate (Hexa-μ-formato(O,O')-μ4-oxo tetraberyllium(II) )

Basic beryllium formate has been used for the CVD preparation of BeO films []

Basic beryllium acetate (Hexa-μ-acetato(O,O')-μ4-oxo tetraberyllium(II) )

Molecular structure of beryllyium oxoacetate Be4O(OAc)6

Structure

Basic beryllium acetateBe4O(OAc)6 has a distinctive crystal structure [[i],[ii]]

Synthesis:

Basic beryllium carbonate treatment with hot acetic acid. [[iii]]

The basic berylium acetate Be4O(OAc)6 is insoluble in water but soluble in chloroform, consistent with it being nonpolar.

It melts (285°C) and sublimes (330°C) in a vacuum without decomposition, making it potential precursor for the CVD of Be-containing layers
