Synthesis of Nanoporous Cubic In(CN)3 and In1-xGax(CN)3 and Corresponding Inclusion Compounds

摘要: Anhydrous In(CN)3 and In1-xGax(CN)3 phases with empty Prussian-blue-type structures have been prepared via low-temperature solution methods utilizing molecular templating agents. Quantitative X-ray powder diffraction was used to refine the cubic structure in which In is octahedrally surrounded by an average of three C N atoms. The symmetry Pm3m, a = 5.627(1) A, In−(C,N) C−N bond lengths are 2.251(1) 1.125(1) respectively. compound reversibly incorporates krypton atoms into cavities form In(CN)3·Kr, readily identified diffraction. Similar inclusion systems n-hexane porous framework also synthesized. solid solutions formed suitable combinations binary lattice constants adjustable between 5.293 A for Ga(CN)3 In(CN)3. variation parameters composition obeys Vegard's Law.
