4-Iodoanilinium perchlorate 18-crown-6 clathrate
In the title compound, C(6)H(7)IN(+)·ClO(4) (-)·C(12)H(24)O(6), the proton-ated 4-iodo-anilinium cation inter-acts with the 18-crown-6 through three N-H⋯O hydrogen bonds, forming a rotator-stator-like structure. The cation, anion and 18-crown-6 mol-ecule all have crystallographically imposed mirror symmetry.
متن کامل2,4,5-Trichloroanilinium perchlorate 18-crown-6 clathrate
In the title compound, C(6)H(5)Cl(3)N(+)·ClO(4) (-)·C(12)H(24)O(6), the perchlorate anion is disordered over two orientations in a 0.666 (17):0.334 (17) ratio. The ammonium group of the organic cation inserts into the crown ether ring and forms three bifurcated N-H⋯(O,O) hydrogen bonds to generate a supra-molecular complex. The macrocycle has approximate D(3d) local symmetry.

In the title compound, C(7)H(10)N(+)·ClO(4) (-)·C(20)H(24)O(6), the proton-ated benzyl-amine cation forms a rotator-stator complex with the 18-crown-6 (1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne) mol-ecule via N-H⋯O hydrogen bonds. The cations are associated via weak C-H⋯π inter-actions, forming chains parallel to [011], while the perclorate anions are located between these chains.
متن کامل4-Bromoanilinium perchlorate 18-crown-6 clathrate
The reaction of 4-bromo-aniline, 18-crown-6, and perchloric acid in methanol yields the title compound, C(6)H(7)BrN(+)·ClO(4) (-)·C(12)H(24)O(6), in which the protonated -NH(3) (+) group forms three bifurcated N-H⋯O hydrogen bonds to the O atoms of the crown ether.
متن کاملDimethylammonium perchlorate 18-crown-6 monohydrate clathrate
The reaction of dimethyl-amine, 18-crown-6, and perchloric acid in methanol yields the title compound, C(2)H(8)N(+)·ClO(4) (-)·C(12)H(24)O(6)·H(2)O. The dimethyl-ammonium cation and the water mol-ecule inter-act with the 18-crown-6 unit: N-H⋯O hydrogen bonds are formed between the ammonium NH(2) (+) group and four O atoms of the crown ether, while the water mol-ecule on the other side of 18-cro...
