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). It is a conjugate base of oxalic acid.
Gallium compounds are compounds containing the element gallium. These compounds are found primarily in the +3 oxidation state . The +1 oxidation state is also found in some compounds, although it is less common than it is for gallium's heavier congeners indium and thallium .

Gallium is a chemical element; it has the symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, [ 13 ] gallium is in group 13 of the periodic table and is similar to the other metals of the group ( aluminium , indium , and thallium ).
Gallium(III) oxide is an inorganic compound and ultra-wide-bandgap semiconductor with the formula Ga 2 O 3. It is actively studied for applications in power electronics, phosphors, and gas sensing. [5] [6] [7] The compound has several polymorphs, of which the monoclinic β-phase is the most stable.
They contain gallium in oxidation states +1, +2 and +3. Ga 3 Cl 7 This compound contains the Ga 2 Cl 7 − ion, which has a structure similar to the dichromate, Cr 2 O 7 2−, ion with two tetrahedrally coordinated gallium atoms sharing a corner. The compound can be formulated as gallium(I) heptachlorodigallate(III), Ga I Ga III 2 Cl 7. [1]
