Ethyl-enediammonium dichloro-iodide chloride.

ABSTRACT: The asymmetric unit of the crystal structure of the title compound, C(2)H(10)N(2) (2+)·Cl(2)I(-)·Cl(-), contains two ethyl-ene-diammonium cations, two [ICl(2)](-) anions and two Cl(-) anions, of which one cation, one [ICl(2)](-) anion and one Cl(-) anion have site symmetry 2, with the mid-point of the C-C bond of the cation, the I atom of [ICl(2)](-) anion and the Cl(-) anion located on the twofold rotation axes. The two independent cations show different conformations, the N-C-C-N torsion angles being 160.1 (2) and -73.1 (4)°. The crystal structure is stabilized by extensive inter-molecular N-H⋯Cl hydrogen bonding.

Ethyl-enediammonium dichloride.

Project description:The title ionic compound, C(2)H(10)N(2) (2+)·2Cl(-), crystallizes with a center of symmetry within the cation. Each of the positively charged ammonium ends of the mol-ecule is trigonally hydrogen bonded to three different chloride counter-ions, while each of the chloride ions is trigonally hydrogen bonded to three different ethyl-enediammonium cations. The hydrogen-bonding network leads to stabilization of the structure.

Ethyl-enediammonium tetraaquadi-sulfatomagnesium(II).

Project description:The title compound, [NH(3)(CH(2))(2)NH(3)][Mg(SO(4))(2)(H(2)O)(4)], was synthesized by the slow evaporation method. Its crystal structure can be described as an alternate stacking of inorganic layers of tetra-aqua-bis(sulfato-O)magnesium [Mg(SO(4))(2)(H(2)O)(4)](2-) anions ( symmetry) and organic layers of [NH(3)(CH(2))(2)NH(3)](2+) cations along the crystallographic b axis. The anions, built up from tetrahedral SO(4) units and octahedral Mg(H(2)O)(4)O(2) units, and the cations are linked together through N-H?O hydrogen bonds, forming a three-dimensional network. O-H?O inter-actions are also present.

2-[Bis(2-amino-ethyl)amino]ethanaminium chloride dichloro-methane solvate.

Project description:In the title compound, C(6)H(19)N(4) (+)·Cl(-)·CH(2)Cl(2), the non-H atoms of the ammonium ion show non-crystallographic C(3) symmetry. The chloride ion is embedded in a framework of seven crystallographically independent hydrogen bonds (five N-H⋯Cl and two C-H⋯Cl), which form layers parallel to the (100) plane. Two N---H...N bonds also occur.

Yttrium ethyl-enediammonium squarate tetra-hydrate.

Project description:The title compound, {(C(2)H(10)N(2))(1.5)[Y(C(4)O(4))(3)(H(2)O)(4)]}(n) {system-atic name: catena-poly[sesqui(ethyl-enediammonium) [[tetra-aquabis-(squarato-?O)yttrium(III)]-?-squarato-?(2)O:O']]}, was synthesized by slow evaporation of an acid solution. The asymetric unit contains one yttrium cation in an anti-prismatic environnement, three squarate groups, one and a half protonated ethyl-enediamine mol-ecules and four water mol-ecules. YO(8) polyhedra are connected through bis-(mono-dentate) squarates, leading to infinite zigzag chains, in between which are located ammonium groups. A framework of hydrogen bonds between protonated amine N atoms, water mol-ecules and squarate anions ensures the cohesion of the structure.

Bis(ethyl-enediammonium) tetra-deca-borate.

Project description:The title compound, 2C(2)H(10)N(2) (2+)·B(14)O(20)(OH)(6) (4-), consists of a centrosymmetric tetra-deca-borate anion and two ethyl-enediammonium cations. The anions are inter-connected through strong O-H⋯O hydrogen bonds into a three-dimensional supra-molecular network with channels along [100], [010], [001] and [111]. The diprotonated cations reside in the channels and inter-act with the inorganic framework by extensive N-H⋯O hydrogen bonds.

Ethyl-enediammonium tetra-aqua-disulfato-cadmate.

Project description:The crystal structure of the title compound, [NH(3)(CH(2))(2)NH(3)][Cd(SO(4))(2)(H(2)O)(4)], consists of [Cd(SO(4))(2)(H(2)O)(4)](2-) anions that are built from octa-hedral Cd(H(2)O)(4)O(2) and SO(4) tetra-hedral units linked by corner sharing. The ethyl-ene-diamminium cations are linked to the anions via N-H⋯O hydrogen bonds. The asymmetric unit contains one-half of the compound, the other half being related to the first by an inversion centre. The crystal structure presents alternate stacking of the inorganic and organic layers along the crystallographic b axis. The structure cohesion and stability is further assured by O(water)-H⋯O hydrogen bonds.

Ethyl-enediammonium tetra-bromido-mercurate(II) monohydrate.

Project description:The Hg(II) atoms in the crystal structure of the title compound, (C(2)H(10)N(2))[HgBr(4)]·H(2)O, are tetra-hedrally coordinated by four Br atoms and the resulting [HgBr(4)](2-) ions are inter-connected to the [NH(3)-CH(2)-CH(2)-NH(3)](2+) ions and water mol-ecules by N-H⋯Br and O-H⋯Br bonds, forming a three-dimensional network. N-H⋯O inter-actions are also present. The observed three different Hg-Br distances of 2.5597 (6), 2.6862 (8) and 2.6923 (8) Å in the tetra-bromo-mercurate unit are due to the connection of Br atoms to different numbers of H atoms. The Hg, O and two Br atoms are located on a crystallographic mirror plane. The cation has symmetry with the center of the C-C bond lying on a crystallographic center of inversion.

Poly[ethyl-enediammonium [tris-[?(3)-hydrogenphosphato(2-)]dicadmium] monohydrate].

Project description:The title compound, {(C(2)H(10)N(2))[Cd(2)(HPO(4))(3)]·H(2)O}(n), was synthesized under hydro-thermal conditions.

The ethyl-ene-diammonium cation and the water mol-ecule are located between two adjacent inorganic layers and ensure the cohesion of the structure via N-H?O and O-H?O hydrogen bonds.
