Abstract

Anhydrous In(CN)₃ and In_1-x Ga_x (CN) )₃ phase 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 In(CN)₃ cubic structure in which In is octahedrally surrounded by an average of three C and three N atoms. The symmetry is Pm3̄m, aα = 5.627(1) A, and the In - (C,N) and C-N bond lengths are 2.251(1) and 1.125 Å, respectively. The compound reversibly incorporates krypton atoms into the empty cavities to form In(CN) ₃·Kr, which is readily identified by powder diffraction. Similar inclusion systems with n-hexane in the porous framework are also synthesized. In_-xGax(CN) ₃ solid solution are formed by suitable combination of the binary systems and have lattice constant adjustable between 5.293 Å for Ga(CN) ₃ and 5.627(1) Å for In(CN) ₃. The variation of the lattice parameters with compositon obeys Vegard's Law.
