Tetracyanoborate ([1] tetracyanidoborate,[2] or tetracyanoboranuide) is an anion or salt of this anion. It has four cyano groups attached to a central boron atom. The formula is [B(CN)4]−.

The anion is weakly coordinating and stable in conjunction with the hydronium ion H3O+.[3]

Tetracyanoborate can form ionic liquids with unsymmetrical quaternary nitrogen cyclic cations.[4] These are under investigation as carbon dioxide absorbers for use in carbon capture and storage.[5] They are also used as electrolytes in supercapacitors and electric batteries.[6]

Tetracyanoborate compounds were first made by Eduard Bernhardt and team in 2000 after previous failed attempts in the 1950s.[7]

Production

[edit]

Tetrabutylammonium bromide can react with boron trihalides and potassium cyanide to yield tetrabutylammonium tetracyanoborate.[7]

Tetrafluoroborate salts can react with Me3SiCN when catalysed with Lewis acids to substitute fluoride with cyanide yielding tetracyanoborates.[8]

Hydrogen tetracyanoborate can react with metal oxides or hydroxides to yield tetracyanoborate salts.

Potassium tetracyanoborate can react in a metastases with another metal salt to yield insoluble tetracyanoborates.

A low cost generation route is to use potassium fluoroborate with excess lithium chloride and potassium cyanide with a metal hydroxide.[7]

[edit]

The related hexacyanodiborane(6) dianion [B2(CN)6]2− has a boron to boron bond, and forms salts.[9]

The tricyanoborate dianion B(CN)32− can be used to generate various other substituted tricyanoborate ions.

The tetrakis(trifluoromethyl)borate anion, [B(CF3)4]- is also weakly coordinating and stable.[10]
