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.
