title: 4-Chloro-anilinium tetra-fluoro-borate 18-crown-6 clathrate.
abstract: In the title compound, C(6)H(7)ClN(+)·BF(4) (-)·C(12)H(24)O(6), the complete cation is generated by crystallographic mirror symmetry, with two C atoms and the N and Cl atoms lying on the mirror plane. The complete crown ether is also generated by mirror symmetry, as is the anion (in which the B and two F atoms lie on the mirror plane). The -NH(3) (+) group of the cation inserts into the crown-ether ring and forms bifurcated N-H⋯(O,O) hydrogen bonds. The H atoms of the -NH(3) (+) group were modelled as disordered across the mirror plane.
