Gadolinium oxalate is the oxalate of gadolinium, with the chemical formula Gd 2 (C 2 O 4) 3. Its hydrate can be prepared by the reaction of gadolinium nitrate and oxalic acid . [ 1 ]
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.

It is a reducing agent [9] and its conjugate bases hydrogen oxalate (HC 2 O − 4) and oxalate (C 2 O 2− 4) are chelating agents for metal cations. It is used as a cleaning agent, especially for the removal of rust, because it forms a water-soluble ferric iron complex, the ferrioxalate ion.
Gallium trichloride is a common starting reagent for the formation of organogallium compounds, such as in carbogallation reactions. [15] Gallium trichloride reacts with lithium cyclopentadienide in diethyl ether to form the trigonal planar gallium cyclopentadienyl complex GaCp 3. Gallium(I) forms complexes with arene ligands such as ...
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.

Gallium trichloride is formed by the reaction of gallium metal with chlorine gas. [34] Unlike the trifluoride, gallium(III) chloride exists as dimeric molecules, Ga 2 Cl 6, with a melting point of 78 °C. Equivalent compounds are formed with bromine and iodine, Ga 2 Br 6 and Ga 2 I 6. [33]: 133
