Potassium hexacyanochromate(III) is a coordination compound with the formula K3[Cr(CN)6]. It consists of three potassium cations and a central hexacyanometallate with [Cr(CN)6]3- anion. It is a yellow air-stable paramagnetic solid. It´s not stable at higher temperatures forming chromium(III) hydroxide precipitate.The salt is prepared by treating Cr(II) derivatives which are substitutionally labile with cyanide salts followed by air oxidation.
