Gallium: Inorganic ChemistryBased in part on the article Gallium: Inorganic Chemistry by Andrew R. Barron which appeared in theEncyclopedia of Inorganic Chemistry, First Edition.

“…The lactate, tartrate, and citrate have all been used in physiological studies involving gallium radioisotopes. According to NMR studies ( 1 H, 13 C, and 71 Ga), the 1:1 Ga/citrate complex predominates at low pH (<2), while oligomeric species exist in the range pH 2 -6, unlike the aluminum citrate system. 134 The structural characterization for the gallium citrate complex has recently been realized; the gallium citrate complex (NH 4 ) 3 [Ga(C 6 H 5 O 7 ) 2 ]·4H 2 O hydrate has been prepared from the reaction of gallium nitrate with citric acid.…”

“…Furthermore, given the steric hindrance about the gallium center in complexes formulated as GaX 3 (NH 3 ) n (X = Cl, n = 1, 3, 5, 6, 7, 14; X = Br, n = 1, 5, 7, 9, 14; X = I, n = 1, 5,6,7,9,13,20), it is likely that where n is greater than 3 these are also cationic solvates. …”

First Gallium and Indium Crystal Structures of Curcuminoid Homoleptic Complexes: All-Different Ligand Stereochemistry and Cytotoxic Potential

“…Gallium (Ga) and indium (In) are widely utilized in various applications [1], including violet lasers, photodetectors, UV cameras, and transistor devices [2]. Additionally, these elements find application in LEDs [3,4].…”

“…However, exploration of their applications in the field of biology and medicine has been limited. Gallium (III) complexes have attracted attention due to their potential biological properties, as previously reported [2]. While gallium nitrate has received FDA approval for cancer treatments [7], reports on the biological applications of gallium complexes remain scarce.…”

“…The investigation of Group 13 (Al, Ga, In, Tl) concerning metal cluster compounds [2], and ligands such as β-diketiminate [20] or acetylacetonates (ACAC), has been extensively used as supporting ligands, conferring protection to prevent secondary reactions or nucleophilic attacks on the metal ion [21]. Therefore, the chemistry of organogallium and organoindium compounds using other ligands such as curcumin or curcuminoids widens the knowledge of this type of metallodrug.…”
