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

ABSTRACT: 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.

Project description:In the title compound, [Zr(C(11)H(10)NO)(4)]·2C(3)H(7)NO, the Zr(IV) ion is coordinated by four bidentate 5,7-dimethylquinolin-8-olate ligands in a slightly distorted square-anti-prismatic coordination environment.

One of the DMF solvent mol-ecules was refined as disordered over three sets of sites, with refined occupancies in the ratio of 0.391?(9):0.342?(10):0.267?(7).

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.

Crystal structure of di-μ-chloro-acetato-hexa-kis-(di-methyl-formamide)-tetra-kis-(μ-N,2-dioxido-benzene-1-carboximidato)tetra-manganese(III)disodium dimethyl-formamide disolvate.

Project description:The synthesis, crystal structure, and FT-IR data for the title compound, [Na2Mn4(C2H2ClO2)2(C7H4NO3)4(C3H7NO)6]·2C3H7NO or Na2(O2CCH2Cl)2[12-MCMn(III) N(shi)-4](DMF)6·2DMF, where MC is metallacrown, shi(3-) is salicyl-hydroximate, and DMF is N,N-di-methyl-formamide, is reported. The macrocyclic metallacrown consists of an -[Mn(III)-N-O]4- ring repeat unit and the metallacrown captures two Na(+) ions in the central cavity above and below the plane of the metallacrown. Each Na(+) ion is seven-coordinate and is bridged to two ring Mn(III) ions, through either a coordinating DMF mol-ecule or a chloro-acetate anion. The ring Mn(III) ions have either a tetra-gonally distorted octa-hedral geometry or a distorted square-pyramidal geometry. Weak C-H⋯O inter-actions, in addition to pure van der Waals forces, contribute to the overall packing of the mol-ecules. The complete molecule has inversion symmetry and is disordered over two sets of sites with an occupancy ratio of 0.8783 (7):0.1217 (7). The solvent molecule is also disordered over two sets of sites, with an occupancy ratio of 0.615 (5):0.385 (5).
