[Co(en)(3)][In-3(H2PO4)(6)(HPO4)(3)]center dot H2O: A new layered indium phosphate templated by cobalt complex

摘要

A new layered indium phosphate [Co(en)(3)][In-3(H2PO4)(6)(HPO4)(3)].H2O (1) has been synthesized solvothermally by using a racemic mix of chiral metal complex Co(en)(3)Cl-3 as a template. Its structure is determined by single-crystal X-ray diffraction analysis and further characterized by X-ray powder diffraction, ICP, NMR and TG analyses. The inorganic layer is built up by alternation of In-centred octahedra (InO6) and P-centered tetrahedra (PO3(OH), PO2(OH)(2), PO2(=O)(OH) and PO(=O)(OH)(2)) forming a 4.12-net. The metal complex cations locate in the interlayer region and interact with the host network through H-bonds. It is the first indium phosphate compound templated by a transition-metal complex and is isostructural with GaPO-CJ14.
