Tetra-kis[μ₂-1,1,1,3,3,3-hexa-fluoro-2-(tri-fluoro-meth-yl)propan-2-olato]tetra-kis-(μ₃-2-methyl-propan-2-olato)octa-copper(I).

ABSTRACT: The title compound, [Cu₈(C₄H₉O)₄(C₄F₉O)₄], crystallizes in the monoclinic space group, P2₁/n and contains a self-assembly of two C₁₆H₁₈Cu₄F₁₈O₄ units linked by bridging tert-butyl groups [Cu-O bonds of length 2.3779 (15) and 2.4248 (15) Å], generating a centrosymmetric dimer. The asymmetrical unit, C₁₆H₁₈Cu₄F₁₈O₄, contains an almost square-planar arrangement of the four Cu atoms linked by bridging tert-butyl and perfluorinated tert-butyl groups with Cu-Cu distances ranging from 2.7108 (4) to 2.7612 (4) Å and Cu -Cu-Cu angle values close to 90° [ranging from 89.459 (10)° to 90.025 (11)°]. These dimers are further linked by weak C-H⋯F and F⋯F inter-actions. As is commonly encountered in perfluorinated tert-butyl groups, one of the CF₃ groups is disordered and was refined with two equivalent conformations with occupancies of 0.74 (3) and 0.26 (3).

Tetra-kis(diethyl ether)tetra-?(4)-oxido-octa-kis-(penta-fluoro-phen-yl)octa-zinc.

Project description:Mol-ecules of the title compound, [Zn(8)(C(6)F(5))(8)O(4)(C(4)H(10)O)(4)], are located on a special position of site symmetry [Formula: see text]. As a result, there is just one quarter-mol-ecule in the asymmetric unit. The title compound features a Zn(4)O(4) cube. Each Zn atom in the cube carries a pentafluorophenyl substituent. Each O atom is bonded to a further Zn atom, which is connected to a pentafluorophenyl substituent and the O atom of a diethyl ether mol-ecule. All ether C atoms are disordered over two sets of sites with a site occupation factor of 0.51?(2) for the major occupied site.

Poly[[tetra-kis-(μ-2-anilinobenzoato-κO:O')tetra-μ(1,1,1)-azido-tetra-μ(1,1)-azido-octa-methano-lhexa-nickel(II)] methanol hexa-solvate].

Project description:The crystal structure of the title compound, [Ni(6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)]·6CH(3)OH, consists of a centrosymmetric hexa-nuclear [Ni(II) (6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)] mol-ecule and six methanol solvent mol-ecules. In the hexa-nuclear unit, the six octa-hedrally coordinated Ni(II) atoms are linked by four μ(1,1,1)-azide and four μ(1,1)-azide bridges, forming a face-sharing Ni(6)N(8) tetra-cubane-like unit with four missing corners. The Ni(II) atoms are further bridged by four μ(1,2)-carboxalate groups. Neighbouring hexa-nuclear units are connected via N-H⋯O hydrogen-bonding inter-actions into a three-dimensional structure. Although the H atoms of the methanol OH groups could not be located, O⋯N/O contacts between 2.65 and 2.86 Å suggest that these mol-ecules participate in hydrogen bonding.

Tetra-ammonium bis-(metforminium) di-μ6-oxido-tetra-μ3-oxido-tetra-deca-μ2-oxido-octa-oxidodeca-vanadium(V) hexa-hydrate.

Project description:The title compound, (NH4)4(C4H12N5)2[V10O28]·6H2O, crystallizes with the deca-vanadate anion placed on an inversion centre in space group P .

A second shell includes metforminium monocations with a twisted geometry, also forming numerous inter-molecular hydrogen bonds. The complex three-dimensional network of non-covalent inter-actions affords a crystal structure in which the cations and anions are densely packed.

Project description:The title compound, [Li(2)Mg(C(4)H(3)F(6)O)(4)(C(4)H(10)O(2))(2)], forms as a white crystalline powder by-product of the reaction of lithium 1,1,1,3,3,3-hexa-fluoro-2-methyl-2-propoxide with Mo(N-2,6-Me(2)-C(6)H(3))(CHCMe(2)Ph)(O(3)SCF(3))(2)·2DME (DME is 1,2-dimethoxyethane) contaminated with MgCl(2). The crystal structure of this compound contains half a mol-ecule in the asymmetric unit, with a twofold rotation axis through the central Mg(2+) cation. The four 1,1,1,3,3,3-hexa-fluoro-2-methyl-propan-2-olate ligands serve as bridging ligands connecting the Li(+) and Mg(2+) cations. The Li(+) cation is additionally stabilized by a DME ligand. This results in a distorted tetra-hedral ligand field around both the Mg(2+) and Li(+) cations.

Bis-(di-meth-oxy-ethane-1κ2O,O')penta-kis-(1,1,1,3,3,3-hexa-fluoro-propan-2-olato)-2κ3O,3κ2O-μ-hy-droxido-1:3κ2O-μ3-oxido-1:2:3κ3O-magnesiumdialuminium.

Project description:Partial hydrolysis of a sample of [Mg(dme)3][Al(hfip)4]2 crystals led to the formation of the title complex, [Mg(dme)2{HOAl(hfip)2OAl(hfip)3}] (dme = di-meth-oxy-ethane and hfipH = hexa-fluoro-iso-propanol) or [Mg(C4H10O2)2O(OH)Al2(C3HF6O)5]. The magnesium cation exhibits a distorted octa-hedral coordination with two bidentate di-meth-oxy-ethane mol-ecules and a dinuclear aluminate anion, coordinated to Mg2+ via oxido and hydroxido units. The anion is an oxido-bridged species, [HOAl(hfip)2(μ-O)Al(hfip)3]2-, with one Al3+ cation tetra-hedrally coordinated by an oxido (O2-) anion, a hydroxido anion, and two hfip groups, whereas the second Al3+ cation is coordinated by the oxido anion and three hfip groups.

Poly[tetrakis(μ-1,1,1,3,3,3-hexafluoropropan-2-olato)iron(II)dipotassium].

Project description:The title compound, [K2Fe{OCH(CF3)2}4] n , was formed from the reaction of potassium hexa-fluoro-isopropoxide with iron(II) chloride in toluene. The Fe(II) atom has a highly distorted tetra-hedral coordination environment. All four of the non-equivalent hexa-fluoro-isoprop-oxy O atoms link the Fe(II) atoms to one of the K(+) atoms in an alternating chain of Fe-O-K-O fused four-membered rings, with K-Fe distances of 3.715 (2) and 3.717 (2) Å. This K(+) atom is also bridged to eight of the F atoms. The other K(+) atom is bonded to only two of the O atoms, but has seven short K⋯F contacts, one of which links the chains into a three-dimensional arrangement. Weak hydrogen bonding between the lone H atoms on the hexa-fluoro-isoprop-oxy groups and F atoms is also present. The crystal studied was refined as an inversion twin.

Bis{[amino-(iminium-yl)meth-yl]urea} tetra-kis-{2-[(di-methyl-amino)(iminium-yl)meth-yl]guanidine} di-μ6-oxido-tetra-μ3-oxido-tetra-deca-μ2-oxido-octa-oxidodeca-vanadium(V) tetra-hydrate.

Project description:The title compound, (C4H12N5)4(C2H7N4O)2[V10O28]·4H2O, is a by-product obtained by reacting ammonium metavanadate(V), metformin hydro-chloride and acetic acid in the presence of sodium hypochlorite, at pH = 5. The crystal structure comprises a deca-vanadate(V) anion (V10O28)6- lying on an inversion centre in space group P , while cations and solvent water mol-ecules are placed in general positions, surrounding the anion, and forming numerous N-H⋯O and O-H⋯O hydrogen bonds. Metforminium (C4H12N5)+ and guanylurea (C2H7N4O)+ cations display the expected shape. Inter-estingly, in physiology the latter cation is known to be the main metabolite of the former one. The reported structure thus supports the role of sodium hypochlorite as an oxidizing reagent being able to degrade metformin hydro-chloride to form guanylurea.
