Catena-Poly[triethyl-ammonium [[tetra-?-acetato-?(8)O:O'-dicuprate(II)]-?-acetato-?(2)O:O'] tetra-hydro-furan monosolvate].

ABSTRACT: In the title compound, {[(C(2)H(5))(3)NH][Cu(2)(CH(3)COO)(5)]·C(4)H(8)O}(n), the two different Cu(II) atoms are coordinated in a pseudo-square-pyramidal environment by five O atoms from the acetate ligands. Neighbouring pairs of Cu(II) atoms are linked by four basally coordinating bridging acetate ligands as in the crystal structure of copper acetate monohydrate. The fifth, apically coordinating ligand links two of the dicopper tetra-acetate paddlewheel-units together, thus building a linear coordination polymer which extends along [10-1]. Each apical acetate ligand is linked by an N-H?O hydrogen bond to a triethyl-ammonium cation. Weak C-H?O hydrogen bonding interactions also occur.

Project description:The title complex, [Cu(4)(C(5)H(12)NO)(2)(C(2)H(3)O(2))(6)(C(4)H(8)O)(2)](n), consists of dinuclear [Cu(2)(C(5)H(12)NO)(2)(THF)(2)] (THF is tetra-hydro-furan) and [Cu(2)(CH(3)COO)(4)] units linked through acetate ions, generating parallel one-dimensional polymeric chains propagating in the [10] direction. In the first dinuclear unit, Cu(II) ions related by inversion symmetry are bridged by two 3-(dimethyl-amino)propan-1-olate ligands. Likewise, a pair of inversion-related Cu(II) ions are bridged by four acetate groups. The crystallographically independent Cu centers are linked to one another by a single bridging acetate group, generating an infinite chain. The distorted square-pyramidal coordination of the first metal center is completed with an apical THF mol-ecule, with a long Cu-O bond length of 2.476?(5)?Å. The geometry around the other metal atom is close to octa-hedral, and the Cu?Cu separation in this unit is 2.652?(1)?Å. The distance between the metal centers in the first dinuclear unit is considerably longer [3.068?(1)?Å], suggesting little or no bonding inter-action. The Cu?Cu separation between two acetate-bridged independent Cu centers is 4.860?(2)?Å. The THF mol-ecule has methyl-ene groups disordered over two positions, with occupancies of 0.608?(13) and 0.392?(13).

Bis(triethyl-ammonium) tetra-chlorido-cobaltate(II).

Project description:The crystal structure of the title compound, (C(6)H(16)N)(2)[CoCl(4)], is comprised of a tetrahedral [CoCl(4)](2-) anion and two independent triethyl-ammonium cations. The latter are featureless while the [CoCl(4)](2-) anion exhibits typical Co-Cl bond lengths [2.2428?(15)-2.2847?(16)?Å] and a Cl-Co-Cl angular range of 107.58?(6)-112.73?(7)°. In the crystal, N-H?Cl hydrogen bonds between the two crystallographically independent cations and the [CoCl(4)](2-) anion generate discrete ion triplets. The two Co-Cl bonds involved in these inter-actions are slightly longer than the remaining two.

Project description:The title chain polymer compound, [GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2)](n), was obtained in the reaction of GaBr(3) with Me(3)SiOLi in toluene/tetra-hydro-furan. The Ga(III) atom, located on a twofold rotation axis, is coordinated by four trimethyl-silanolate ligands and has a distorted tetra-hedral geometry. The Li(I) atom is four coordinated by one bridging Br atom located on an inversion centre, two trimethyl-silanolate ligands and one tetra-hydro-furane mol-ecule in a distorted tetra-hedral geometry. The polymeric chains extend along [001]. The tetra-hydro-furane mol-ecule is disordered over two positions with site-occupancy factors of 0.57?(2) and 0.43?(2).

Epalrestat tetra-hydro-furan monosolvate: crystal structure and phase transition.

Project description:The title compound, epalrestat {systematic name: (5Z)-5-[(2E)-2-methyl-3-phenyl-prop-2-en-1-yl-idene]-4-oxo-2-sulfanyl-idene-1,3-thia-zolidine-3-acetic acid}, crystallized as a tetra-hydro-furan monosolvate, C15H13NO3S2·C4H8O. Epalrestat, an important drug for diabetic neuropathy, has been reported to exist in polymphic, solvated and co-crystal forms. In the mol-ecule reported here, the phenyl ring is inclined to the rhodamine ring by 22.31?(9)°, and the acetic acid group is almost normal to the rhodamine ring, making a dihedral angle of 88.66?(11)°. In the crystal, pairs of O-H?O hydrogen bonds are observed between the carb-oxy-lic acid groups of epalerstat mol-ecules, forming inversion dimers with an R22(8) loop. The dimers are linked by pairs of C-H?O hydrogen bonds, forming chains along [101]. The solvate mol-ecules are linked to the chain by a C-H?O(tetra-hydro-furan) hydrogen bond. A combination of thermal analysis and powder X-ray diffraction revealed that title compound desolvated into epalerstat Form II. One C atom of the tetra-hydro-furan solvate mol-ecule is positionally disordered and has a refined occupancy ratio of 0.527?(18):0.473?(18).

Triethyl-ammonium hexa-?(2)-acetato-?O:O'-diacetato-?O-aqua-?(3)-oxido-triferrate(III) toluene monosolvate.

Project description:The title compound, (C(6)H(16)N)[Fe(3)(CH(3)CO(2))(8)O(H(2)O)]·C(7)H(8), was serendipitously crystallized from a reaction of disilanol with iron(II) acetate. The trinuclear acetatoferrate(III) anion has a triethyl-ammonium cation as the counterion. The three Fe atoms lie on the vertices of a regular triangle and are octa-hedrally coordinated. The complete coordination of the anion includes shared ligands among the three metal ions: a central tribridging O atom and six bidentate bridging acetyl groups. The six-coordinations of two of the metal ions are completed by a monodentate acetate ligand, whereas that of the third metal ion is completed by a water mol-ecule. The uncoordinated triethyl-ammonium cation is involved in N-H?O hydrogen bonding to a singly coordinated acetyl group. The coordinated aqua mol-ecule is involved in bifurcated O-H?O hydrogen bonding. C-H?O inter-actions are also observed. The toluene solvent molecule is disordered over two sets of sites in a 0.609?(11):0.391?(11) ratio.

Crystal structure of 3-(tri-phenyl-phosphoranyl-idene)-2,5-di-hydro-furan-2,5-dione tetra-hydro-furan monosolvate.

Project description:The title pseudo-polymorph of 3-(tri-phenyl-phospho-ranyl-idene)-2,5-di-hydro-furan-2,5-dione crystallizes with a tetra-hydro-furan solvent mol-ecule, viz. C22H17O3P·C4H8O. The succinic anhydride ring is approximately planar (r.m.s. deviation = 0.032?Å). The tetra-hydro-furan mol-ecule is disordered over two orientations about a pseudo-twofold axis with refined occupancy ratio 0.718?(4):0.282?(4). In the crystal, C-H?O hydrogen bonds link mol-ecules of the di-hydro-furan-2,5-dione derivative into chains parallel to the b axis and arranged into layers stacked along [100] alternating with hydrogen-bonded tetra-hydro-furan layers.

Chloridotris[?(2)-2-(dimethyl-amino)-ethano-lato]-?(3)-hydroxido-tri-?(2)-trifluoro-acetato-tetra-copper(II) tetra-hydro-furan solvate.

Project description:The title compound, [Cu(4)(C(2)F(3)O(2))(3)(C(4)H(10)NO)(3)Cl(OH)]·C(4)H(8)O or [Cu(4)(TFA)(3)(dmae)(3)Cl(OH)]·THF (dmae is dimeth-yl-amino-ethano-late, TFA is trifluoro-acetate and THF is tetra-hydro-furan), has an approximate mol-ecular threefold symmetry with three equivalent {Cu(dmae)(TFA)} units bridging between a Cu-Cl and a hydroxide unit, with the latter two lying on the mol-ecular threefold axis. However, in the solid state, the tetranuclear complex has C(i) symmetry. The Cu atom bonded to the Cl atom has a distorted tetra-hedral geometry. The other three Cu atoms have distorted square-pyramidal geometries with an NO(4) coordination environment. The bonds within the CuNO(3) base of the pyramid range from 1.953?(2) to 2.033?(3)?Å, while the apical Cu-O bonds are significantly longer, ranging from 2.286?(2) to 2.377?(2)?Å. The square-pyramidal geometries are augmented by weak inter-actions towards a sixth O atom, forming a highly distorted octa-hedral coordination environment [long Cu-O distances = 2.712?(2)-2.824?(2)?Å]. The hydroxide group is hydrogen bonded to the tetra-hydro-furan solvent mol-ecule. One of the -CF(3) groups shows minor disorder over two positions, with a refined occupancy ratio of 0.894?(4):0.106?(5).

(1,4,7,10,13,16-Hexaoxa-cyclo-octa-decane-?(6) O)bis-(tetra-hydro-furan-?O)potassium bis-[(1,2,3,4-?)-anthracene]cobalt(-I) tetra-hydro-furan monosolvate.

Project description:The asymmetric unit of the title compound, [K(C12H24O6)(C4H8O)2][Co(C14H10)2]·C4H8O, consists of one cationic potassium complex, one anionic cobalt dianthracene complex and one tetra-hydro-furan solvent mol-ecule. The potassium cation is situated at the centre of an 18-crown-6 mol-ecule and between two tetra-hydro-furan mol-ecules, the latter coordin-ating above and below the mean plane formed by the O atoms of the crown ether mol-ecule. The Co atom is coordinated by eight C atoms of two anthracene mol-ecules in an ?(4) manner. The third free tetra-hydro-furan mol-ecule shows orientational disorder on two partially occupied positions [occupancy ratio 0.561?(8):0.439?(8)].

catena-Poly[dieth-yl(2-hydroxy-ethyl)-ammonium [[tetra-?-acetato-?O:O'-dicuprate(II)(Cu-Cu)]-?-acetato-?O:O'] dichloro-methane solvate].

Project description:The title compound, {(C(6)H(16)NO)[Cu(2)(CH(3)COO)(5)]·CH(2)Cl(2)}(n), consists of acetate-bridged Cu(2)(CH(3)COO)(4) units that are connected via another acetate anion at each terminus to form infinite anionic [{Cu(2)(CH(3)COO)(4)}(CH(3)COO)](n) chains along [100]. The connecting acetate is hydrogen bonded to the dieth-yl(2-hydroxy-ethyl)ammonium cation, and the dichloro-methane solvent mol-ecule fills the remaining voids in the structure. The O-Cu-Cu angles along the polymeric chain are nearly linear [175.49?(5)°], but individual O-Cu-Cu-O units along the chain are bent and rotated against each other at the bridging acetate ion. Translation of each Cu(2)(CH(3)COO)(4) unit along the chain, represented by the least-squares plane of the two copper ions along with four of the acetate O atoms, rotated these units by 35.16?(3)°.
