Beryllium(II) forms many complexes with bidentate ligands containing oxygen-donor atoms. [52] The species [Be 3 O(H 2 PO 4) 6] 2-is notable for having a 3-coordinate oxide ion at its center. Basic beryllium acetate, Be 4 O(OAc) 6, has an oxide ion surrounded by a tetrahedron of beryllium atoms.
Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is an electrical insulator with a higher thermal conductivity than any other non-metal except diamond , and exceeds that of most metals. [ 12 ]
"Basic acetates" consist of an ensemble of metal centres bound to a central oxide ion, and a collection of acetate ligands. 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 ...
Beryllium fluoride is the inorganic compound with the formula Be F 2. ... Tetrafluoroberyllate is a robust ion, which allows its purification by precipitation of ...
Beryllium chloride is an inorganic compound with the formula BeCl 2. It is a colourless, hygroscopic solid that dissolves well in many polar solvents. Its properties are similar to those of aluminium chloride , due to beryllium 's diagonal relationship with aluminium .
The reaction with lithium hydride (in which the hydride ion is the Lewis base), forms sequentially LiBeH 3 and Li 2 BeH 4. [3] The latter contains the tetrahydridoberyllate(2-) anion BeH 2− 4. Beryllium hydride reacts with trimethylamine, N(CH 3) 3 to form a dimeric adduct with bridging hydrides. [11]
Basic beryllium carbonate is a mixed salt, which can be prepared by the reaction of beryllium sulfate and ammonium carbonate, and contains both carbonate and hydroxide ions, with formula Be 2 CO 3 (OH) 2. [6] It is believed that in the older literature this is probably what was referred to as beryllium carbonate. [6]
Beryllium bromide is the chemical compound with the formula BeBr 2. It is very hygroscopic and dissolves well in water . The Be 2+ cation, which is relevant to BeBr 2 , is characterized by the highest known charge density (Z/r = 6.45), making it one of the hardest cations and a very strong Lewis acid .
