Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4.This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4).
Copper(II) oxalate are inorganic compounds with the chemical formula CuC 2 O 4 (H 2 O) x. The value of x can be 0, 0.44, and 1. The value of x can be 0, 0.44, and 1. Two of these species are found as secondary minerals (degradation of minerals), whewellite (monohydrate) and moolooite (0.44 hydrate). [ 3 ]

Oxalate sulfates are mixed anion compounds containing oxalate and sulfate. They are mostly transparent, and any colour comes from the cations. They are mostly transparent, and any colour comes from the cations.
An oxalate nitrate is a chemical compound or salt that contains oxalate and nitrate anions (NO 3-and C 2 O 4 2-). These are mixed anion compounds. Some have third anions. Oxalate acts as a ligand, which normally complexes two metal atoms.
Sodium oxalate, or disodium oxalate, is a chemical compound with the chemical formula Na 2 C 2 O 4. It is the sodium salt of oxalic acid. It contains sodium cations Na + and oxalate anions C 2 O 2− 4. It is a white, crystalline, odorless solid, that decomposes above 290 °C. [2]
The carbonate oxalates are mixed anion compounds that contain both carbonate (CO 3) and oxalate (C 2 O 4) anions. Most compounds incorporate large trivalent metal ions, such as the rare earth elements. Some carbonate oxalate compounds of variable composition are formed by heating oxalates. [1]
The measured magnetic moment of 4.65 B.M. suggests that the chromium ion does not form a Cr-Cr bond and has a high-spin octahedral coordination geometry. This would be consistent with the structure of other linear polymeric metal(II) oxalates of general formula MC 2 O 4 ·2H 2 O (M = Mg, Fe, etc.). [2]
