Inclusion Compounds of Thiourea and Paralkylated Ammonium Salts. Part VII. Hydrogen-Bonded Host Lattices Constructed from Thiourea and Anionic Species Derived from Benzoic Acid

New inclusion complexes (n-C₃H₇)₄N⁺C₆H₅CO ₂ ^– · 3(NH₂)₂CS (1), (n-C₄H₉)₄N⁺(C₆H₅CO₂)₂H]^–·6(NH₂)₂CS (2) and (C₂H₅)₄N⁺C₆H₅CO ₂ ^– ·(NH₂)₂CS (3) have been prepared and characterized by X-ray crystallography. Crystal data, MoK radiation: 1, space group P2₁2₁2₁, Z = 4, a = 8.544(3), b = 14.588(4), c = 24.448(4) Å, and R1 = 0.062 for 1536 observed data; 2, space group Pbcn, Z = 4, a = 24.938(3), b = 8.911(1), c = 23.733(9) Å, and R1 = 0.055 for 2132 observed data; 3, space group P2₁2₁2₁, Z = 4, a = 9.996(2), b = 10.122(4), c = 18.350(2) Å, and R1 = 0.049 for 1180 observed data. In the crystal structure of 1, the (n-C₃H₇)₄N⁺ cations are stacked in a single column and accommodated within each channel built up by wide thiourea ribbons and benzoate ions via N—H···O hydrogen bonds. In the crystal structure of 2, the tetrabutylammonium cations are arranged in a zigzag column within each channel built of parallel corrugated thiourea layers that are inter-linked by dimeric (C₆H₅CO₂)₂H]^– groups through N—H·O hydrogen bonds. In compound 3 the (C₂H₅)₄N⁺ cations are accommodated in pseudo-channels generated from infinitely extended thiourea-benzoate composite ribbons.
