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).
Organogallium chemistry is the chemistry of organometallic compounds containing a carbon to gallium (Ga) chemical bond. Despite their high toxicity [ citation needed ] , organogallium compounds have some use in organic synthesis .

Gallylenes are a class of gallium species which are electronically neutral and in the +1-oxidation state. [1] [2] This broad definition may include many gallium species, such as oligomeric gallium compounds in which the gallium atoms are coordinated to each other, but these classes of compounds are often referred to as gallanes.
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).
The chemical composition of gallium monoiodide was not determined until the early to mid-2010s despite its simple synthesis. In 2012, the pale green gallium monoiodide was determined to be a combination of gallium metal and gallium(I,III) iodide, having the chemical composition [Ga 0] 2 [Ga +][GaI 4 −]. [3]
Gallium can form compounds with the oxidation states +1, +2 and +3. Indium is like gallium, but its +1 compounds are more stable than those of the lighter elements. The strength of the inert-pair effect is maximal in thallium, which is generally only stable in the oxidation state of +1, although the +3 state is seen in some compounds.
Gallium(II) sulfide, GaS, is a chemical compound of gallium and sulfur. The normal form of gallium(II) sulfide as made from the elements has a hexagonal layer structure containing Ga 2 4+ units which have a Ga-Ga distance of 248pm. [1] This layer structure is similar to GaTe, GaSe and InSe. [1]
