Bis(tetra-ethyl-ammonium) bis-(hydrogen l-tartrate) l-tartaric acid monohydrate.

ABSTRACT: In the title compound, 2C(8)H(20)N(+)·2C(4)H(5)O(6) (-)·C(4)H(6)O(6)·H(2)O, the presence of the two tetra-ethyl-ammonium cations is balanced by two hydrogen l-tartrate anions. Also present in the asymmetric unit are a mol-ecule of l-tartaric acid and a water mol-ecule. The various components are linked by O-H?O hydrogen bonds. In the crystal, two-dimensional networks are formed via O-H?O hydrogen bonds and C-H?O inter-actions involving the water mol-ecule, the hydrogen l-tartrate anions and the l-tartaric acid mol-ecules. These layers, which stack along [001], are separated by tetra-ethyl-ammonium cations. The latter are also involved in C-H?O inter-actions with the anions and the l-tartaric acid and water mol-ecules participating in the two-dimensional network.

Project description:In the crystal structure of the title hydrated salt, 2C(4)H(12)N(+)·C(2)O(4) (2-)·H(2)O, the two independent cations, the anion and the water mol-ecule all lie on special positions of m site symmetry. In both cations, the mirror plane passes through the nitrogen atom and two methyl groups; in the anion, the mirror plane passes through two carbon and two oxygen atoms. The anions and water mol-ecules inter-act by O-H?O hydrogen bonding, forming a chain running along the b axis.

Tetra-ethyl-ammonium 4-hy-droxy-benzoate monohydrate.

Project description:In the title compound, C(8)H(20)N(+)·C(7)H(5)O(3) (-)·H(2)O, the carboxyl-ate group is slightly out of the plane of the parent benzene ring, the C-C-C-O torsion angles being 2.3?(2) and 2.0?(2)°. The carboxyl-ate group and the hy-droxy group form O-H?O hydrogen bonds, generating a head-to-tail chain along the b axis. Neighbouring hydrogen-bonded chains are linked by the water mol-ecule, generating two independent O-H?O donor hydrogen bonds. The carboxyl-ate group thus constructs a hydrogen-bonded host layer parallel to (10[Formula: see text]). The tetra-ethyl-ammonium cation is contained between these layers, forming a sandwich-like structure with an approximate inter-layer distance of 10.03?Å.

Project description:Crystals of the title compound, (C(6)H(5)CH(2)CH(2)NH(3))(2)[CoCl(4)], were grown by the solvent-evaporation method. This inorganic-organic hybrid compound exhibits a layered structure in which isolated CoCl(4) inorganic layers alternate with bilayers of phenylethylammonium cations. Although the inorganic anion is zero-dimensional, the layered structure is stabilized via N-H?Cl hydrogen bonds. The CoCl(4) tetra-hedra connect to the cations through N-H?Cl hydrogen bonds, building a two-dimensional network extending parallel to (010).

Project description:The title compound, (C(8)H(20)N)[Mn(2)(C(6)H(5)O)(3)(CO)(6)], was synthesized from [Mn(CO)(3)(CH(3)CN)(3)]BF(4) and (C(8)H(20)N)(OC(6)H(5)). The binuclear anion exhibits a pseudo-threefold symmetry and contains two six-coordinate Mn atoms. Each metal atom is coordinated by three facially oriented CO ligands and three doubly-bridging phenolate ligands. The average O-Mn-O bond angle is 74.9?(7)° in the Mn(2)O(3) metal-phenolate dimeric core, yielding a distorted octa-hedron for each metal.

Bis(tetra-ethyl-ammonium) oxalate dihydrate.

Project description:The title compound, 2C(8)H(20)N(+)·C(2)O(4) (2-)·2H(2)O, synthesized by neutralizing H(2)C(2)O(4)·2H(2)O with (C(2)H(5))(4)NOH in a 1:2 molar ratio, is a deliquescent solid. The oxalate ion is nonplanar, with a dihedral angle between carboxyl-ate groups of 64.37?(2)°. O-H?O hydrogen bonds of moderate strength link the O atoms of the water mol-ecules and the oxalate ions into rings parallel to the c axis. The rings exhibit the graph-set motif R(4) (4)(12). In addition, there are weak C-H?O inter-actions in the crystal structure.

Crystal structure of (S)-sec-butyl-ammonium l-tartrate monohydrate.

Project description:The title hydrated mol-ecular salt, C4H12N+·C4H5O6-·H2O, was prepared by deprotonation of enanti-opure l-tartaric acid with racemic sec-butyl-amine in water. Only one enanti-omer was observed crystallographically, resulting from the combination of (S)-sec-butyl-amine with l-tartaric acid. The sec-butyl-ammonium moiety is disordered over two conformations related by rotation around the CH-CH2 bond; the refined occupancy ratio is 0.68?(1):0.32?(1). In the crystal, mol-ecules are linked through a network of O-H?O and N-H?O hydrogen-bonding inter-actions, between the ammonium H atoms, the tartrate hy-droxy H atoms, and the inter-stitial water, forming a three-dimensional supra-molecular structure.

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].

Project description:In the title compound, C(8)H(20)N(+)·CHO(3) (-)·3H(2)O, the bicarbon-ate anion, which has a small mean deviation from the plane of 0.0014?Å, fully utilises its three O and one H atom to form various O-H?O hydrogen bonds with the three water mol-ecules in the asymmetric unit, generating a hydrogen-bonded layer, which extends along (10[Formula: see text]). The tetra-ethyl-ammonium cations, as the guest species, are accommodated between every two neighboring layers, constructing a sandwich-like structure with an inter-layer distance of 7.28?Å.
