Project description:In the title compound, [Zr(C(5)H(4)F(3)O(2))(4)]·C(7)H(8), the Zr atom is in a square-anti-prismatic coordination geometry that comprises four O,O'-bidentate trifluoro-acetyl-acetonate ligands.

Crystal structure of tetra-kis-(1,1,1,5,5,5-hexa-fluoro-acetyl-acetonato)hafnium(IV).

Project description:The crystal structure of the title compound, [Hf(C5HF6O2)4], has been determined. The asymmetric unit contains two Hf(hfac)4 mol-ecules (hfac = 1,1,1,5,5,5-hexa-fluoro-acetyl-acetonate); both are located on general positions and have identical structures apart from the disorder involving three CF3 groups in one of the two mol-ecules. The mol-ecules of Hf(hfac)4 are arranged in layers that are parallel to the ab plane, and the coordination geometry of each hafnium(IV) center is a distorted square anti-prism. An inter-esting aspect of the structure is that the hfac ligands are arranged so that the Hf(hfac)4 mol-ecules have idealized 2 point symmetry, in which two of the hfac groups bridge between the two squares. Although all other M(β-diketonate)4 compounds of Hf (and Zr) also have square-anti-prismatic geometries; in almost all of them the ligands are arranged so that the mol-ecules have 222 point symmetry (in which none of the hfac ligands bridges between the two squares). The factors that favor one structure over another are not clear.

Di-?-hydroxido-bis-[tris-(4,4,4-trifluoro-1-phenyl-acetyl-acetonato-?O,O')hafnium(IV)] dimethyl-formamide disolvate.

Project description:The binuclear molecule of the title compound, [Hf(2)(C(10)H(6)F(3)O(2))(6)(OH)(2)]·2C(3)H(7)NO, lies across an inversion centre and contains a Hf(IV) atom which is eight-coordinated and surrounded by three chelating ?-diketonato tris-(4,4,4-trifluoro-1-phenyl-acetyl-acetonate (tfba(-)) ligands and two bridging OH(-) groups in a distorted square-anti-prismatic geometry. The Hf-O bond lengths vary from 2.073?(2) to 2.244?(2)?Å and the O-Hf-O bite angles vary from 73.49?(9) to 75.60?(9)°. Weak O-H?O hydrogen-bonding inter-actions are observed between the bridging hy-droxy groups and the dimethylformamide solvent mol-ecules. The unit cell contains solvent-accessible voids of 131?Å(3), but the residual electron density in the difference Fourier map suggests no solvent mol-ecule occupies this void.

Tetra-kis(quinolin-8-olato-?N,O)hafnium(IV) toluene disolvate.

Project description:In the title compound, [Hf(C(9)H(6)NO)(4)]·2C(7)H(8), the hafnium metal centre is coordinated by four N,O-donating bidentate quinolin-8-olate ligands arranged to give a square-anti-prismatic coordination polyhedron with a slightly distorted dodeca-hedral geometry. The average Hf-O and Hf-N distances are 2.096?(3) and 2.398?(3)?Å, respectively, and the average O-Hf-N bite angle is 70.99?(11)°. The crystal packing is controlled by ?-? inter-actions between quinoline ligands of neighbouring mol-ecules and hydrogen-bonding inter-actions. The inter-planar distances vary between 3.138?(1) and 3.208?(2)?Å, while the centroid-centroid distances range from 3.576?(1) to 4.074?(1)?Å.

Pyridinium tetra-kis-(1,1,1-trifluoro-pentane-2,4-dionato)dysprosate.

Project description:In the anion of the title compound, (C(5)H(6)N)[Dy(C(5)H(4)F(3)O(2))(4)], the central metal ion, Dy(3+), is coordinated by four bidentate 1,1,1-trifluoro-pentane-2,4-dionate (TAA) ligands, forming an approximate square-anti-prismatic configuration. The pyridin-ium cation is connected to the complex ion by an N-H?O hydrogen bond and electrostatic inter-actions in the crystal. There are two kinds of disorder in the structure, one involving rotational disorder of a CF(3) group [occupancy ratio 0.560?(15):0.440?(15)] and the other involving an exchange between a CF(3) group and CH(3) group within a given bidentate ligand (occupancy ratio 0.64:0.36).

fac-Tricarbon-yl(pyridine-?N)(1,1,1-trifluoro-acetyl-acetonato-?O,O')rhenium(I).

Project description:In the title compound, [Re(C(5)H(4)F(3)O(2))(C(5)H(5)N)(CO)(3)], the Re(I) atom is six-coordinated owing to bonding by three carbonyl ligands arranged in a fac configuration, two O atoms from the bidentate 1,1,1-trifluoro-acetyl-acetonate ligand and an N atom from a pyridine ligand. In the crystal, the mol-ecules pack in layers, diagonally, in a head-to-tail fashion across the ab plane. These layers are stabilsed by inter-molecular C-H?O and C-H?F hydrogen bonds.

cyclo-Tetra-?-oxido-tetra-kis-[(acetyl-acetonato-?O,O')bis-(ethano-lato-?O)niobium(V)].

Project description:The asymmetric unit of the title tetra-nuclear niobium(V) compound, [Nb(4)(C(2)H(5)O)(8)(C(5)H(7)O(2))(4)O(4)], contains two Nb(V) atoms, two bridging O atoms, two acetyl-acetonate and four ethano-late ligands. Each Nb(V) atom is six-coordinated by the bridging O atoms, two ethano-late and one chelating acetyl-acetonate ligands. The Nb-O distances vary between 1.817?(2) and 2.201?(2)?Å and the O-Nb-O angles vary between 78.88?(8) and 102.78?(9)°, illustrating the significant distortion from ideal ocahedral geometry. The rest of the tetra-nuclear unit is generated through an inversion centre. The C atoms of two of the ethano-late mol-ecules are disordered over two sites [occupancy ratio 0.601?(12):0.399?(12)].

Tetra-kis(5,7-dimethyl-quinolin-8-olato-?N,O)hafnium(IV) dimethyl-formamide disolvate.

Project description:In the title compound, [Hf(C(11)H(10)NO)(4)]·2C(3)H(7)NO, the Hf(IV) atom is coordinated by four N,O-donating bidentate 5,7-dimethyl-8-quinolino-late (Ox(-)) ligands arranged to give a distorted square-anti-prismatic coordination polyhedron. The average Hf-O and Hf-N distances are 2.098 and 2.298?Å, respectively, and the average O-Hf-N bite angle is 70.2°. The crystal packing is controlled by ?-? inter-actions between Ox(-) ligands of neighbouring mol-ecules, giving rise to a three-dimensional supra-molecular grid network. The inter-planar distances vary from 3.441?(1) to 3.509?(1)?Å, while the centroid-centroid distances vary from 3.688?(2) to 3.759?(12)?Å. A non-classical C-H?O hydrogen bond is observed between the complex and one of the solvate mol-ecules.

Tetra-ethyl-ammonium tetra-kis-(1,1,1,5,5,5-hexa-fluoro-acetyl-acetonato)terbate(III).

Project description:The title compound, (C(8)H(20)N)[Tb(C(5)HF(6)O(2))(4)], is a tetrakis ?-diketonate complex of hexa-fluoro-acetyl-acetone with terbium(III), and tetra-ethyl-ammonium as the counter-ion. This compound shows typical green terbium(III) luminescence upon excitation at about 335?nm. The coordination geometry around the Tb(III) atom is a slightly distorted square anti-prism. One hexa-fluoro-acetyl-acetone ligand has a disordered CF(3) group [occupancies of 0.575?(4) and 0.425?(4)]. A three-dimensional network is built up by linkage of Tb(III) complexes via C-H?F inter-actions.

(Acetyl-acetonato-κO,O')chlorido-trimethano-latoniobium(V).

Project description:In the title compound, [Nb(CH(3)O)(3)(C(5)H(7)O(2))Cl], the Nb(V) atom is coordinated by two O atoms from the chelating acetyl-acetonate ligand, three O atoms from the methano-late groups and one chloride ligand. The octa-hedral environment around niobium is slightly distorted with Nb-O distances in the range 1.8603 (15)-2.1083 (15) Å and an Nb-Cl distance of 2.4693 (9) Å. The O-Nb-O angles vary between 80.74 (6) and 100.82 (7)°, while the trans Cl-Nb-O angle is 167.60 (5)°. There are no hydrogen bonds observed, only an inter-molecular C-H⋯O inter-action.
