Title: Crystal structure of di-μ-hydroxido-κ ⁴ O : O -bis[bis(acetylacetonato-κ ² O , O ')cobalt(III)]

Abstract

The dinuclear title complex, [Co₂(C₅H₇O₂)₄(μ-OH)₂] or [Co(acac)₂(μ-OH)]₂, where acac is acetylacetonate, is centrosymmetric with half of the molecule per asymmetric unit. The molecular structure is a dimer of octahedrally coordinated Co^IIIatoms with four O atoms from two chelating acac ligands and two O atoms from bridging hydroxide ligands. The crystal packing features weak C—H...O interactions between neighboring molecules, leading to the formation of chains normal to theacplane. The hydroxide H atoms are not involved in hydrogen bonding because of the bulky acac ligands. This is the first crystal structure reported of a dimeric transition metal bis-acac complex with OH^-as the bridging group.

Crystal structure of bis(acetylacetonato-κ²O,O')(tetrahydrofuran-κO)(trifluoromethanesulfonato-κO)iron(III)

Journal Article Richers, Casseday P. ; Bertke, Jeffery A. ; Rauchfuss, Thomas B. - Acta Crystallographica. Section E, Crystallographic Communications

The mononuclear title complex, [Fe(CF₃O₃S)(C₅H₇O₂)₂(C₄H₈O)] or [Fe(acac)₂(OTf)(THF)] (acac = acetylacetonate; OTf = trifluoromethanesulfonate; THF = tetrahydrofuran), (I), consists of one six-coordinate Fe³⁺atom in a slightly distorted octahedral environment [Fe—O bond-length range = 1.9517 (11)–2.0781 (11) Å]. The triflate ligand was found to be disordered over two sets of sites, with a site-occupancy ratio of 0.622 (16):0.378 (16). Weak intermolecular C—H...O and C—H...F hydrogen-bonding interactions generate a two-dimensional supramolecular structure lying parallel to (100). This is only the second crystal structure reported of a mononuclear bis(acetylacetonato)iron(III) complex.

Crystal structure of a trigonal polymorph of aquadioxidobis(pentane-2,4-dionato-κ ² O , O ′)uranium(VI)

Journal Article Hernandez, Alejandro ; Chakraborty, Indranil ; Ortega, Gabriela ; ... - Acta Crystallographica. Section E, Crystallographic Communications

The title compound, [UO ₂ (acac) ₂ (H ₂ O)] consists of a uranyl(VI) unit ([O=U=O] ²⁺ ) coordinated to two monoanionic acetylacetonate (acac, C ₅ H ₇ O ₂ ) ligands and one water molecule. The asymmetric unit includes a one-half of a uranium atom, one oxido ion, one-half of a water molecule and one acac ligand. The coordination about the uranium atom is distorted pentagonal–bipyramidal. The acac ligands and O _w atom comprise the equatorial plane, while the uranyl O atoms occupy the axial positions. Intermolecular hydrogen bonding between complexes results in the formation of two-dimensional hexagonal voidmore »« less

Hydrogenolysis of Dinuclear PCN ^R Ligated Pd ^II μ‐Hydroxides and Their Mononuclear Pd ^II Hydroxide Analogues

Journal Article Bailey, Wilson D. ; Phearman, Alexander S. ; Luconi, Lapo ; ... - Chemistry - A European Journal

Abstract The hydrogenolysis of mono‐ and dinuclear Pd ^II hydroxides was investigated both experimentally and computationally. It was found that the dinuclear μ‐hydroxide complexes {[(PCN ^R )Pd] ₂ (μ‐OH)}(OTf) (PCN ^H =1‐[3‐[(di‐ tert ‐butylphosphino)methyl]phenyl]‐1 H ‐pyrazole; PCN ^Me =1‐[3‐[(di‐ tert ‐butylphosphino)methyl]phenyl]‐5‐methyl‐1 H ‐pyrazole) react with H ₂ to form the analogous dinuclear hydride species {[(PCN ^R )Pd] ₂ (μ‐H)}(OTf). The dinuclear μ‐hydride complexes were fully characterized, and are rare examples of structurally characterized unsupported singly bridged μ‐H Pd ^II dimers. The {[(PCN ^Me )Pd] ₂ (μ‐OH)}(OTf) hydrogenolysis mechanism was investigated through experiments and computations. The hydrogenolysis of the mononuclear complexmore »« less

Journal Article Kazhdan, Daniel - Acta Crystallographica. Section E

The title compound, [Yb₂(CF₃O₃S)(C₁₀H₁₅)₂(OH)_2-(C₁₂H₁₂N₂)₂](C₂₄H₂₀B)∙C₁₂H₁₂N₂, crystallizes as a half-sandwich complex with a bridging trifluoromethanesulfonate as well as two bridging hydroxide groups. The bound bipyridine ligands have N—C—C—N torsion angles of 13.1 (9) and 12.1 (8). The structure also contains an uncoordinated 5,50 - dimethyl-2,20 -bipyridine molecule with an N—C—C—N torsion angle of 169.5 (7). The triply bridged Yb centers are 3.5990 (4) Å apart. The Yb—N bond lengths are in the range 2.389 (6)–2.424 (5) Å.

Anhydrous yttrium acetylacetonate and the course of thermal dehydration' of Y(acac)[sub 3][center dot]3H[sub 2]O

Journal Article Barash, E H ; Coan, P S ; Lobkovsky, E B ; ... - Inorganic Chemistry; (United States)

Hydrocarbon-soluble [Y(acac)[sub 3]][sub n] (acac = acetylacetonate) is produced in high yield by treatment of Y[N(SiMe[sub 3])[sub 2]][sub 3] with 3 equiv of Hacac in hydrocarbon solvent. Variable-temperature [sup 1]H and [sup 89]Y NMR studies suggest that the degree of aggregation, n, of this compound is four. Attempted slow crystallization of this compound from hexanes gives, as the least-soluble material, the product of adventitious partial hydrolysis: Y[sub 4](OH)[sub 2](acac)[sub 10]. Its structure was established by X-ray diffraction as Y[sub 4]([mu][sub 3]-OH)[sub 2]([mu]-acac)[sub 6](acac)[sub 4]. This centrosymmetric aggregate has a diamond-shaped Y[sub 4] core, with [mu][sub 3]-OH groups lying above andmore »« less
