Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa)Infobox references Chromium(II) oxide (CrO) is an inorganic compound composed of chromium and oxygen.[1] It is a black powder that crystallises in the rock salt structure.[2] Hypophosphites may reduce chromium(III) oxide to chromium(II) oxide:
- H3PO2 + 2 Cr2O3 → 4 CrO + H3PO4
It is readily oxidized by the atmosphere.
