Abstract

A novel inclusion compound, [C₆H₁₁NH₃][Cu₂(CN)₃] · 2C₆H₅NH₂, has been synthesized and structurally characterized by X-ray crystallographic methods. It crystallizes in the monoclinic space group P2₁/n with a = 8.839(1), b = 18.894(2), c = 14.080(3) Å, β = 93.76(1)°, V = 2346.5(7) Å³, Z = 4. The structure is composed of the anionic layered two-dimensional host [Cu₂(CN)₃]⁻ and the cationic onium guest [C₆H₁₁NH₃]⁺ and neutral guests, C₆H₅NH₂. Each Cu(I) atom is bonded to three cyanide ligands and exhibits trigonal coordination. Cu(I)-CN-Cu(I) bridges from puckered hexagons with all edges shared. The cyclohexylammonium and aniline guests are situated between host layer sheets. The cyclohexylammonium ion has a chair conformation and lies perpendicular to the host layer. The aniline molecules are arranged perpendicular and inclined at approximately 45° to the host layer, respectively. Both guest molecules are held together by a network of hydrogen bonds.
