The first organically templated gallium phosphite–oxalates: Synthesis, structures, and characterizationseer

Three new gallium phosphite–oxalates formula as (C6N2H14)2[Ga2(OH)2(C2O4)2(HPO3)2]·2H2O (1), (C6N2H18)0.5[Ga(OH)(C2O4)0.5(HPO3)] (2), and Ga(C2O4)0.5(C3N2H4)(HPO3) (3) have been hydrothermally synthesized by controlling the pH value of the reaction system. Compound 1 possesses a one-dimensional ladder-like chain structure, in which the C2O42− anion is coordinated to one Ga center and acts as mono-bidentate ligand. In 2 and 3, the C2O42− anions serve as bis-bidentates ligands bridging between two Ga atoms to form the two-dimensional layered structures. Furthermore, compound 3 displays a neutral layered network, which is decorated by the directly coordinated organic ligand.
