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.
Compounds containing Ga–Ga bonds are true gallium(II) compounds, such as GaS (which can be formulated as Ga 2 4+ (S 2−) 2) and the dioxan complex Ga 2 Cl 4 (C 4 H 8 O 2) 2. [1] There are also compounds of gallium with negative oxidation states, ranging from -5 to -1, most of these compounds being magnesium gallides (Mg x Ga y).

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 ]
Gallium does not occur as a free element in nature, but rather as gallium(III) compounds in trace amounts in zinc ores (such as sphalerite) and in bauxite. Elemental gallium is a liquid at temperatures greater than 29.76 °C (85.57 °F), and will melt in a person's hands at normal human body temperature of 37.0 °C (98.6 °F).
Although most compounds are referred to by their IUPAC systematic names ... Barium oxalate – Ba(C 2 O 4) [99] Barium oxide – BaO ... Gallium(III) oxide – Ga 2 O 3;
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
