Benzyl-aminium perchlorate-18-crown-6 (1/1).

ABSTRACT: 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?? inter-actions, forming chains parallel to [011], while the perclorate anions are located between these chains.

Theobrominium perchlorate dibenzo-18-crown-6 3.25-hydrate.

Project description:The co-crystal, C7H9N4O2 (+)·ClO4 (-)·C20H24O6·3.25H2O, consists of theobrominium (3,7-di-methyl-2,6-dioxo-1H-purin-9-ium) cations, perchlorate anions and dibenzo-18-crown-6 and water mol-ecules. The crown ether is in a bent conformation, in which the planes of the aromatic rings subtend an angle of 63.7?(1)°. Inter-molecular O-H?O hydrogen bonding between the water mol-ecules and the O atoms of the cyclic ether delimit an empty space reminiscent of a hollow cage. The water mol-ecules are additionally linked to the cations by N-H?O hydrogen bonding. One of the positions of the water molecules is occupied only fractionally (25%) and is located outside this framework.

Project description: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.

Dimethyl-ammonium perchlorate 18-crown-6 monohydrate clathrate.

Project description: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-crown-6 ring forms O-H⋯O hydrogen bonds with two other O atoms of the crown ether. All conventional donors and acceptors in the cations are thus engaged in hydrogen bonding. The ClO(4) (-) anion is disordered over two sites, and occupancies for the disordered O atoms were fixed at 0.5. In the crystal, the cations and anions are arranged in alternating layers.

4-Ethyl-anilinium perchlorate-18-crown-6 (1/1).

Project description:The asymmetric unit of the title compound, C(8)H(12)N(+)·ClO(4) (-.)C(12)H(24)O(6), contains one half of the cationic [(C(2)H(5)-C(6)H(4)-NH(3))(18-crown-6)](+) moiety and one half of the ClO(4) (-) anion. Two O atoms of the crown ether, four C atoms and the N atom of the ethylanilinium unit and the Cl and two O atoms of the anion lie on a mirror plane. In the crystal structure, the -NH(3) (+) group lies in the 18-crown-6 ring, forming a supra-molecular rotator-stator-like structure linked by intra-molecular N-H⋯O hydrogen bonds. The six O atoms of the crown ether lie approximately in a plane, the mean deviation being 0.1771 (3) Å; the N atom lies approximately 0.855 (3) Å from the centroid of the crown ether ring.
