(C4H12N2)3[Ga4(OH)2(H2PO4)2(HPO4)4(PO4)2]: a new organically templated gallium phosphate
Abstract
The solvothermal reaction of gallium oxide with phosphoric acid in water/ethylene glycol in the presence of piperazine gave the title compound, bis(piperazinium) bis(dihydrogenphosphato)tetra-μ2-hydrogenphosphato-di-μ3-hydroxo-di-μ3-phosphato-tetragallate(III), (C4H12N2)3[Ga4(OH)2(H2PO4)2(HPO4)4(PO4)2]. The compound is isostructural with its FeIII analogue, and contains one-dimensional anionic chains with piperazinium cations lying between them. The tetranuclear anionic building blocks and the piperazinium cations lie on inversion centres.
