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

ABSTRACT: 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.

3-Ammonio-pyridinium tetra-bromido-mercurate(II) monohydrate.

Project description:The asymmetric unit of the title compound, (C(5)H(8)N(2))[HgBr(4)]·H(2)O, consists of one cation, one anion and one water mol-ecule. The anion exhibits a distorted tetra-hedral arrangement about the Hg atom. The crystal structure contains alternating sheets of cations (in the ac plane) and stacks of anions. Several strong hydrogen-bonding inter-actions (pyN-H?Br and C-H?Br; py is pyridine), along with O-H?Br inter-actions, connect the sheets of cations to the stacks of anions. Cation-cation ?-? stacking is also present (C?C distances in the range 3.424-3.865?Å). The shortest Br?Br distance is 3.9527?(9)?Å.

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.

O-H?O inter-actions are also present.

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 structure of this hybrid compound consists of CdO(6), CdO(5) and PO(4) polyhedra arranged so as to build an anionic inorganic layer, namely [Cd(2)(HPO(4))(3)](2-), parallel to the ab plane. The edge-sharing CdO(6) octa-hedra form infinite chains running along the a axis and are linked by CdO(5) and PO(4) polyhedra. 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.

A second monoclinic polymorph of ethyl-enediammonium bis-(hydrogen squarate) monohydrate.

Project description:The title compound, C(2)H(10)N(2) (2+)·2HC(4)O(4) (-)·H(2)O, a new polymorph of ethyl-enediammonium bis-(hydrogen squarate) monohydrate, was synthesized by slow evaporation of an acid solution. The asymetric unit contains two hydrogen squarate anions, two half-mol-ecules of protonated ethyl-enediamine arranged around a twofold axis and one water mol-ecule. In the crystal, N-H?O and O-H?O hydrogen bonds between the hydrogen squarate anions, protonated N atoms from the amine group and water mol-ecules lead to a three-dimensional framework. In particular, the cohesion between the squarate groups is ensured by very short intermolecular hydrogen bonds bonds. The title compound crystallized together with the previously reported polymorph [Mathew et al. (2002 ?). J. Mol. Struct.641, 263-279].
