Ethane-1,2-diaminium 4,5-dichloro-phthalate.

ABSTRACT: In the structure of the title compound, C(2)H(10)N(2) (2+)·C(8)H(2)Cl(2)O(4) (2-), the dications and dianions form hydrogen-bonded ribbon substructures which enclose conjoint cyclic R(2) (1)(7), R(1) (2)(7) and R(4) (2)(8) associations and extend down the c-axis direction. These ribbons inter-associate down b, giving a two-dimensional sheet structure. In the dianions, one of the carboxyl-ate groups is essentially coplanar with the benzene ring, while the other is normal to it [C-C-C-O torsion angles = 177.67?(12) and 81.94?(17)°, respectively].

Ethane-1,2-diaminium dipicrate dihydrate.

Project description:The title compound, C(2)H(10)N(2) (2+)·2C(6)H(2)N(3)O(7) (-)·2H(2)O, crystallizes with a complete picrate anion and half an ethyl-enediammonium dication on a mirror plane, and two half-water mol-ecules (both on a mirror plane) in the asymmetric unit. The N atoms from separate half ethyl-enediammonium dications are in near proximity to a phenolate O atom and two o-NO(2) groups from the picrate anion, which, along with the water mol-ecule form N-H⋯O, O-H⋯O and weak intermolecular C-H⋯O hydrogen bonds that create cyclic patterns with graph-set descriptors R(2) (4)(8), R(4) (4)(12), and R(4) (4)(16). The crystal packing is strongly influenced by these inter-molecular inter-actions between symmetry-related water mol-ecules, the half ethyl-enediammonium dication and the picrate anion, forming a three-dimensional supermolecular structure.

Ethane-1,2-diaminium 4,4'-sulfonyl-dibenzoate.

Project description:In the title salt, C(2)H(10)N(2) (2+)·C(14)H(8)O(6)S(2-), both the ethyl-ene-diaminium cations and the 4,4'-sulfonyl-dibenzoate dianions have crystallographic twofold rotational symmetry. They are inter-linked by aminium N-H?O(carboxyl-ate) hydrogen-bonding associations, giving sheets parallel to (101) and are further linked along [010], forming a three-dimensional structure.

Bis(guanidinium) 4,5-dichloro-phthalate monohydrate.

Project description:In the structure of the title hydrated salt, 2CH(6)N(3) (+)·C(8)H(2)Cl(2)O(4) (2-)·H(2)O, the planes of the carboxyl-ate groups of the dianion are rotated out of the plane of the benzene ring [dihedral angles = 48.42?(10) and 55.64?(9)°]. A duplex-sheet structure is formed through guanidinium-carboxyl-ate N-H?O, guanidinium-water N-H?O and water-carboxyl-ate O-H?O hydrogen-bonding associations.

N (1),N (2)-Di-methyl-ethane-1,2-diaminium dichloride.

Project description:The cation of the title salt, C4H14N2 (2+)·2Cl(-), is located on a crystallographic inversion center and is bis-ected by a mirror plane, with one quarter of the C4H14N2 (2+)·2Cl(-) formula unit being crystallographically unique. he chloride ions also sit on a mirror plane. The conformation of the cation is a regular straight-chain conformation with all non-H atoms in anti positions. In the crystal, hydrogen bonding between N-H groups and chloride anions yields a zigzag ladder-type structure along [010].

Project description:In the title compound, C(4)H(14)N(2) (2+)·2C(7)H(5)O(3) (-), both the N,N-dimethyl-ethylenediamine N atoms are protonated and two 3-hy-droxy-benzoate anions act as counter-ions. In the crystal, anions and cations are linked by a network of N-H?O and O-H?O hydrogen bonds.

N,N'-Bis(2-amino-benz-yl)ethane-1,2-diaminium dinitrate.

Project description:In the title salt, C16H24N4 (2+)·2NO3 (-), both the cation and anion are placed in general positions, although the cation displays non-crystallographic inversion symmetry, with the aliphatic chain extended in an all-trans conformation. The benzene rings are almost parallel, with a dihedral angle between their mean planes of 3.3 (6)°. The nitrate ions are placed in the vicinity of the protonated amine groups, forming efficient N-H⋯O inter-ion hydrogen bonds. Each nitrate ion in the asymmetric unit bridges two symmetry-related cations, forming an R 4 (4)(18) ring, a common motif in organic ammonium nitrate salts. This results in the formation of chains along [010] with alternating cations and anions. The neutral amine groups are involved in slightly weaker N-H⋯O hydrogen bonds with the nitrate O atoms, and there are also a number of C-H⋯O hydrogen bonds present. The resulting supra-molecular structure is based on a two-dimensional network extending in the ab plane.

N,N'-Bis(2-aza-niumylbenz-yl)ethane-1,2-diaminium tetra-chloride.

Project description:The title compound, C(16)H(26)N(4) (4+)·4Cl(-), is based on a fully protonated tetra-amine. In the cation, both benzene rings are connected by an all-trans chain, and the rings are almost parallel, with an angle between the mean planes of 8.34 (12)°. The benzene rings are arranged in such a way that the NH(3) (+) substituents are oriented cis with respect to the central chain. This arrangement is a consequence of multiple N-H⋯Cl hydrogen bonds, involving all N-H groups in the cation and the four independent Cl(-) anions. These contacts have strengths ranging from weak to strong (based on H⋯Cl separations), and generate a complex three-dimensional crystal structure with no preferential crystallographic orientation for the contacts.

Project description:In the title compound, C(2)H(10)N(2) (2+)·C(11)H(10)O(6) (2-), the two acetate groups of the cation form dihedral angles of 74.2?(4) and 63.9?(5)° with the central benzene ring. In the crystal, N-H?O hydrogen bonds link the cations and anions into layers parallel to the ab plane.

Ethane-1,2-diaminium 3,4,5,6-tetra-bromo-2-(methoxy-carbon-yl)benzoate methanol solvate.

Project description:In the title compound, C(2)H(10)N(2) (2+)·2C(9)H(3)Br(4)O(4) (-)·CH(4)O, the N atoms of the ethane-1,2-diamine mol-ecule are protonated. The crystal structure is stabilized by N-H⋯O hydrogen bonds between the ethane-1,2-diaminium cations and 3,4,5,6-tetra-bromo-2-(methoxy-carbon-yl)bromo-benzoate anions, and by O-H⋯O and N-H⋯O hydrogen bonds between the methanol solvate and both the cation and the anion. In addition, the crystal structure exhibits a C-Br⋯O halogen bond [3.20 (3) Å] and a Br⋯Br inter-action [3.560 (2) Å].

N,N'-Bis(3,5-dichloro-benzyl-idene)-ethane-1,2-diamine.

Project description:The mol-ecule of the title Schiff base compound, C(16)H(12)Cl(4)N(2), lies across an inversion centre and adopts an E configuration with respect to the azomethine C=N bond. The imine groups are coplanar with the aromatic rings. Within the mol-ecule, the planar units are parallel but extend in opposite directions from the dimethyl-ene bridge. In the crystal structure, mol-ecules are linked together by inter-molecular C-H⋯Cl hydrogen bonds along the a axis.
