Dimethyl-ammonium tetra-chloridoferrate(III) 18-crown-6 clathrate.

ABSTRACT: The reaction of dimethyl-amine hydro-chloride, 18-crown-6 and ferric chloride in ethanol yields the title compound, (C(2)H(8)N)[FeCl(4)]·C(12)H(24)O(6), which exhibits an unusual supramolecular structure. The protonated dimethyl-amine contains one NH(2) (+) group, resulting in a 1:1 supra-molecular rotator-stator structure (CH(3)-NH(2) (+)-CH(3))(18-crown-6), through N-H?O hydrogen-bonding inter-actions between the ammonium group of the cation and the O atoms of the crown ether. In the crystal, all three components lie on a common crystallographic mirror plane normal to [010].

Project description:The reaction of 4-fluoro-aniline hydro-chloride, 18-crown-6 and ferric chloride in methano-lic solution yields the title compound, (C(6)H(7)FN)[FeCl(4)]·C(12)H(24)O(6), which has an unusual supramolecular structure. N-H⋯O hydrogen-bonding inter-actions between the NH(3) (+) substituents of the 4-fluoro-anilinium cations and the O atoms of the crown ether mol-ecules result in a rotator-stator-like structure.

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.

Methyl-ammonium tetra-fluoridoborate 18-crown-6 clathrate.

Project description:In the title compound, CH(3)NH(3) (+)·BF(4) (-)·C(12)H(24)O(6), the methyl-ammonium cation makes three N-H?O hydrogen bonds to the 18-crown-6 mol-ecule. The -NH(3) (+) and -CH(3) groups of the cation adopt a staggered conformation. The F atoms of the tetra-fluoridoborate anion are disordered over two sets of sites in a 0.519?(11):0.481?(11) ratio. Weak C-H?F inter-actions occur in the crystal, which possibly correlate with the anion disorder.

Project description:The reaction of benzyl-ammonium tetra-fluoro-borate and 18-crown-6 in a methano-lic solution yields the title compound, C(7)H(10)N(+)·BF(4) (-)·C(12)H(24)O(6)O6, which displays a supra-molecular structure. The -NH(3) (+) substituent of the benzyl-ammonium cation forms a 1:1 supra-molecular rotator-stator structure by N-H?O hydrogen-bonding inter-actions.

4-Methyl-anilinium tetra-fluoro-borate 18-crown-6 clathrate.

Project description:In the title compound, C(7)H(10)N(+)·BF(4) (-)·C(12)H(24)O(6), the proton-ated 4-methyl-anilinium cation inter-acts with 18-crown-6 forming a rotator-stator structure, (C(6)H(4)CH(3)NH(3) (+))(18-crown-6), through three bifurcated N-H?(O,O) hydrogen bonds between the ammonium groups of the cations (-NH(3)) and the O atoms of the crown ether mol-ecule. The BF(4) (-) anions, the methyl group and the protonated -NH(3) groups of the 4-methylanilinium lie on a dual axis of rotation. The 18-crown-6 unit is perpendicular to the dual axis of rotation and the mirror plane which contains the dual axis of rotation. The benzene ring of 4-methylanilinium is perpendicular to the mirror plane and parallel to the dual axis.

1,3-Dimethyl-1H-1,2,3-benzotriazol-3-ium tetra-chloridoferrate(III).

Project description:The asymmetric unit of the title salt, (C8H10N3)[FeCl4], contains one 1,3-dimethyl-1H-1,2,3-benzotriazol-3-ium cation and one tetra-chloridoferrate anion. The Fe(III) atom in the anion is tetra-hedrally coordinated by four Cl atoms. In the crystal, inter-actions are observed between the Cl atoms and the triazolium ring [Cl?centroid distances = 3.587?(3) and 3.866?(3)?Å].

Project description:The title salt, (C7H11N2)[FeCl4], consists of one essentially planar (the r.m.s. deviation for all non-H atoms being 0.004?Å) 4-(dimethyl-amino)-pyridinium cation and a tetra-hedral tetra-chloridoferrate(III) anion. The cations and anions are arranged in layers parallel to (010). Besides electrostatic inter-actions, the crystal packing features N-H?Cl and C-H?Cl hydrogen bonds between cations and anions, forming a three-dimensional network.

4-Chloro-anilinium tetra-fluoro-borate 18-crown-6 clathrate.

Project description: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.
