Application In Synthesis of 2,6-DiaminopyridineThis research focused ontrisdiaminopyridinium bis oxalatodioxidovanadatehydrate crystal structure; 2,6-diaminopyridine; bis(oxalato) complexes; crystal structure; dioxovanadate(V); vanadium. The article conveys some information:
Crystals of the title compound, (C5H8N3)3[VO2(C2O4)2]·2.5H2O, a mononuclear VV complex, were obtained by slow evaporation at room temperature of an aqueous solution containing vanadium pentoxide, oxalic acid and 2,6-diaminopyridine. The asym. unit contains one bis(oxalato)dioxovanadate(V) anionic complex, three 2,6-diaminopyridinium cations and two and a half uncoordinated water mols. The mononuclear vanadium(V) anions are connected to the organic cations and water mols. through a strong N-H···O and O-H···O hydrogen-bond network, consolidated by π-π stacking interactions, to form a three-dimensional structure. In the experiment, the researchers used many compounds, for example, 2,6-Diaminopyridine(cas: 141-86-6Application In Synthesis of 2,6-Diaminopyridine)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Application In Synthesis of 2,6-Diaminopyridine
