Not organic. Inorganic compounds are generally structured by ionic bonds and do not contain carbon chemically bound to hydrogen (hydrocarbons) or any of their derivatives. Examples of inorganic compounds include sodium chloride (NaCl) and calcium carbonate (CaCO3) and pure elements (e.g. elemental mercury, elemental lead).

Although containing carbon, carbonates, bicarbonates, carbides, and carbon oxides are considered inorganic compounds.
