Tetra-kis(8-quinolinolato-?N,O)hafnium(IV) dimethyl-formamide solvate monohydrate.

ABSTRACT: In the title compound, [Hf(C(9)H(6)NO)]·C(3)H(7)NO·H(2)O, the hafnium(IV) atom is coordinated by four 8-quinolinolate (Ox) ligands, forming a slightly distorted square-anti-prismatic coordination polyhedron. The crystal packing is controlled by O-H?O and C-H?O hydrogen-bonding inter-actions and ?-? inter-actions between quinoline ligands of neighbouring mol-ecules. The inter-planar distances vary between 3.150?(1) and 3.251?(2)?Å, while centroid-centroid distances vary from 3.589?(1) to 4.1531?(1)?Å.

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.

Redetermination of cyclo-tetra-kis-(μ-5,10,15,20-tetra-4-pyridyl-porphyrinato)tetra-zinc(II) dimethyl-formamide octa-solvate trihydrate at 100 K.

Project description:The structure of the title compound, [Zn(4)(C(40)H(24)N(8))(4)]·8C(3)H(7)NO·3H(2)O, has been redetermined at 100 K. The redetermination is of significantly higher precision and gives further insight into the disorder of pyridyl groups and solvent mol-ecules. The mol-ecules of (5,10,15,20-tetra-4-pyridyl-porphyrinato)zinc(II) (ZnTPyP) form homomolecular cyclic tetra-mers by coordination of a peripheral pyridyl group to the central Zn atom of an adjacent symmetry-related mol-ecule. The tetra-mer so formed exhibits mol-ecular S(4) symmetry and is located about a crystallographic fourfold rotoinversion axis. Severely disordered dimethyl-formamide and water mol-ecules are present in the crystal, the contributions of which were omitted from refinement. Inter-molecular C-H⋯N hydrogen bonding is observed.

Poly[tetra-kis-(dimethyl-formamide)tris(?(4)-terephthalato)trimagnesium].

Project description:The title framework compound, [Mg(3)(C(8)H(4)O(4))(3)(C(3)H(7)NO)(4)](n) or [Mg(3)(bdc)(3)(DMF)(4)](n), was obtained as a side product of the solvothermal reaction of magnesium nitrate, terephthalic acid (bdcH(2)), and 1,3-bis-(4-pyrid-yl)propane in a 1:2:1 ratio in dimethyl-formamide (DMF). The asymmetric unit consists of three Mg(II) cations, three terephthalate anions, and four coordinating DMF mol-ecules. One of the four DMF mol-ecules was refined as disordered over two mutually exclusive positions, with an occupancy rate for the major moiety of 0.923?(4). The three Mg(II) cations possess distorted octa-hedral coordination geometries that form linear Mg trimers. Of the three Mg(II) cations, the central Mg(II) is octa-hedrally coordinated by six different carboxyl-ate O atoms. The terminal Mg(II) cations are bonded to four O atoms of three bdc linkers and to two O atoms of coordinating DMF mol-ecules. The compound has a two-dimensional 3(6)-network structure parallel to (001) that is formed by connection of the Mg trimers as distorted octa-hedral nodes to the bdc ligands as linkers.

Redetermination of diaqua-tetra-kis-(dimethyl-formamide-?O)magnesium dichloride.

Project description:The crystal structure of the title compound, [Mg(C(3)H(7)NO)(4)(H(2)O)(2)]Cl(2), in which the Mg ion lies on a crystallographic inversion centre, confirms that of the previous room-temperature study [Pavanello et al. (1995 ?). Main Group Met. Chem.18, 9-19]. This redetermination at 113?K has improved geometry precision by almost an order of magnitude [e.g. Mg-O(w) (w = water) distances = 2.094?(4) and 2.0899?(7)?Å in the old and new structures, respectively] and allowed the water H atoms to be located and their positions refined. In the crystal, O-H?Cl hydrogen bonds between the two aqua ligands of the complex mol-ecule and neighboring chloride counter-anions generate supra-molecular chains propagating along [010]. The dicationic [Mg(DMF)(4)(H(2)O)(2)] unit (DMF is dimethyl-formamide) adopts a slightly distorted octa-hedral geometry in which the Mg atom is coordinated by four DMF O atoms in a pseudo-tetra-gonal arrangement and two trans aqua 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.

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.

Diaqua-bis-(1,10-phenanthroline)nickel(II) tetra-kis-(cyanido-κC)nickelate(II) tetra-hydro-furan solvate monohydrate.

Project description:The title complex, [Ni(C(12)H(8)N(2))(2)(H(2)O)(2)][Ni(CN)(4)]·C(4)H(8)O·H(2)O, consists of a cationic [Ni(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) unit, an anionic [Ni(CN)(4)](2-) unit, one uncoordinated water and one tetra-hydro-furan mol-ecule. In the cationic unit, the Ni(2+) atom is coordinated by four N atoms and two O atoms from two 1,10-phenanthroline ligands and two water mol-ecules in a distorted octa-hedral coordination environment. In the anionic unit, the Ni(2+) atom is in a square-planar coordination by four C atoms from four monodentate terminal cyanide ligands. O-H⋯N and O-H⋯O hydrogen bonds link neighboring cationic and anionic units, forming a three-dimensional supra-molecular network. The inter-stitial tetra-hydro-furan mol-ecule is independently disordered over two sites in a 1:1 ratio.
