Tetra-n-butylammonium Chloride-Thiourea (1/2), a Layer-Type Inclusion Compound

The structure of a new layer-type inclusion compound, tetra-n-butylammonium chloride-thiourea (1/2) [(ⁿC₄H₉)₄N⁺.Cl^-].2[(NH₂)₂CS], is reported. The thiourea molecules and Cl^- ions form nearly planar layers while the ordered tetra-n-butylammonium ions are sandwiched between them. The layers, which correspond to the (101) family of planes, result from parallel hydrogen-bonded thiourea ribbons that are cross-bridged by Cl^- anions.
