Tetra-ethyl-ammonium bicarbonate trihydrate.

ABSTRACT: 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.

Ammonium tris-(tetra-ethyl-ammonium) hexa-cosa-oxidoocta-molybdate.

Project description:The structure of the title compound, NH(4)(C(8)H(20)N)(3)[Mo(8)O(26)], is built up by discrete cations and anions, with two formula units in the asymmetric unit. The ?-octa-molybdate anions are linked to the ammonium cations via N-H?O hydrogen bonding involving terminal oxide groups and to the tetra-ethyl-ammonium cations via weak C-H?O inter-actions.

Diammonium aqua-(ethyl-ene-diamine-tetra-acetato)iron(II) trihydrate.

Project description:In the title compound, (NH(4))(2)[Fe(C(10)H(12)N(2)O(8))(H(2)O)]·3H(2)O, the Fe(II) center is in a distorted penta-gonal-bipyramidal geometry. Two carboxyl-ate O and two N atoms from the ethyl-enediaminetetra-acetate (EDTA) ion and one O atom from coordinated water comprise the equatorial plane. Two other carboxyl-ate O atoms from the EDTA ion occupy the apical sites. Both ammonium cations and all water mol-ecules function as hydrogen-bond donors, and ten N-H⋯O and nine O-H⋯O hydrogen bonds form a three-dimensional network between the complex anions, cations and the water mol-ecules.

A polymorph of tetra-ethyl-ammonium chloride.

Project description:The structure of the title compound, C(8)H(20)N(+)·Cl(-), is compared with a polymorph that was described earlier in the same space group. Differences in the conformations of the ethyl groups of the cation exist between the polymorphs. This study is given here in order to provide additional unit-cell data for use in qualitative identification of crystalline samples obtained in syntheses in which Et(4)N(+)·Cl(-) is either used or generated.

Tetra-ethyl-ammonium l-malate 1.36-hydrate.

Project description:The asymmetric unit of the title compound, C(8)H(20)N(+)·C(4)H(5)O(5) (-)·1.36H(2)O, contains two independent ion pairs, with similar conformations, and three water mol-ecules of crystallization, one water mol-ecule haing a site-occupancy factor of 0.721 (5). Intra-molecular O-H⋯O hydrogen bonds, involving the hydr-oxy groups and an O atom of each carboxyl-ate anion, generate five-membered rings involving S(5) ring motifs. In the crystal structure, mol-ecules are linked together by water mol-ecules through four-membered O-H⋯O-H⋯O-H inter-actions to form one-dimensional infinite chains along the a axis. Since the mol-ecules are also linked into one-dimensional infinite chains along the b axis, mol-ecular sheets parallel to the (001) plane are created. Overall, the crystal structure is stabilized by two intra-molecular O-H⋯O hydrogen bonds, nine inter-molecular O-H⋯O and ten C-H⋯O hydrogen bonds.

Bis(2-phenyl-ethyl-ammonium) tetra-chloridocobaltate(II).

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).

Tetra-ethyl-ammonium (acetyl-acetonato)bromidotricarbonyl-rhenate(I).

Project description:In the title compound, (C(8)H(20)N)[ReBr(C(5)H(7)O(2))(CO)(3)], the Re(I) atom in the rhenate anion is surrounded by three carbonyl ligands orientated in a facial arrangement, a bromide ligand and an acetyl-acetonate ligand, leading to a distorted octa-hedral ReC(3)BrO(2) coordination with a O-Re-O bite angle of 85.66?(7)°. An array of C-H?O and C-H?Br hydrogen-bonding inter-actions between the cations and the surrounding rhenate anions stabilize the crystal structure.

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.

Tetra-ethyl-ammonium bromidotricarbon-yl(tropolonato)rhenate(I).

Project description:In the title salt, (C(8)H(20)N)[ReBr(C(7)H(5)O(2))(CO)(3)], the Re(I) atom is octa-hedrally surrounded by three facially orientated carbonyl ligands, one bidendate tropolonate ligand and a bromide ligand. The small O-Re-O bite angle of 74.88 (12)° leads to a distortion of the octa-hedral coordination sphere. The bromide ligand and the axial carbonyl ligand are substitutionally disordered over two positions in a 0.922 (3):0.078 (3) ratio. An array of C-H⋯O and C-H⋯Br hydrogen-bonding inter-actions between the cations and neighbouring rhenate anions stabilizes the crystal packing.

Tetra-ethyl-ammonium tri-?-phenolato-bis-[tricarbonyl-manganate(I)].

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.
