Oxalate sulfate

Oxalate sulfates are mixed anion compounds containing oxalate and sulfate. They are mostly transparent, and any colour comes from the cations.

Related compounds include the sulfite oxalates^[1] and oxalate selenates.^[2]

Production

Oxalate sulfates may be deposited from a solution in water of the metal anions and sulfate with oxalic acid when evaporated. Crystals formed this way may be hydrates.^[3]

Properties

Many crystal forms are non-centrosymmetric and have non-linear optical properties.^[3]

When heated, oxalate sulfates will first dehydrate, and then give off carbon dioxide.^[3]
