Beryllium hydroxide, Be(OH) 2, is an amphoteric hydroxide, dissolving in both acids and alkalis. Industrially, it is produced as a by-product in the extraction of beryllium metal from the ores beryl and bertrandite. [7] The natural pure beryllium hydroxide is rare (in form of the mineral behoite, orthorhombic) or very rare (clinobehoite ...
Beryllium hydride (systematically named poly[beryllane(2)] and beryllium dihydride) is an inorganic compound with the chemical formula (BeH 2) n (also written ([BeH 2]) n or BeH 2). This alkaline earth hydride is a colourless solid that is insoluble in solvents that do not decompose it.

The concentration of the first hydrolysis product, [Be(H 2 O) 3 (OH)] +, is less than 1% of the beryllium concentration. The most stable hydrolysis product is the trimeric ion [Be 3 (OH) 3 (H 2 O) 6] 3+. Beryllium hydroxide, Be(OH) 2, is insoluble in water at pH 5 or more. Consequently, beryllium compounds are generally insoluble at biological pH.
Beryllium sulfate normally encountered as the tetrahydrate, [Be(H 2 O) 4]SO 4 is a white crystalline solid. It was first isolated in 1815 by Jons Jakob Berzelius. [4] Beryllium sulfate may be prepared by treating an aqueous solution of many beryllium salts with sulfuric acid, followed by evaporation of the solution and crystallization.
Beryllium monohydride (BeH) is an example of a molecule with a half-bond order according to molecular orbital theory.It is a metastable monoradical species which has only been observed in the gas phase.
Basic beryllium acetate has a tetrahedral Be 4 O 6+ core with acetates (CH 3 CO 2 −) spanning each of the pairs of Be 2+ centres. [3] [4] It consists of interlocking six-membered Be 2 O 3 C rings. The structure is relevant to its considerable stability (the compound is distillable at 330 °C). Schematic structure of basic beryllium acetate
The Be–F bond length is between 145 and 153 pm.The beryllium is sp 3 hybridized, leading to a longer bond than in BeF 2, where beryllium is sp hybridized. [11] In trifluoroberyllates, there are actually BeF 4 tetrahedra arranged in a triangle, so that three fluorine atoms are shared on two tetrahedra each, resulting in a formula of Be 3 F 9.
