Lithium formate (also called lithium methanoate) is an ionic chemical compound with the formula HCOOLi, and a molar mass of 51.95 g/mol. It is potentially nephrotoxic.

Properties

Lithium formate crystalises in the orthorhombic crystal system, with space group Pna2₁. The unit cell has dimensions a = 6.99 Å, b = 6.50 Å and c = 4.85 Å.

The monohydrate loses water to form the anhydrous salt at 94 °C. Decomposition to lithium carbonate, carbon monoxide and hydrogen occurs at 230 °C.
