the epoxidation of olefins with tetra n-butylammonium periodate, n-bu4/nio4, is catalyzed by six different tetrakis (4-substituted phenyl) porphyrinatomanganese(iii) acetate, mn(t4-xpp)oac, complexes in the presence of imidazole as an axial ligand with low to high yields and complete selectivity at room temperature. while the electronic effects of the highly electron-withdrawing no2 substituent...

The two Al atoms in the title compound, [Al(2)(CH(3))(5)(C(23)H(20)NO)], are four-coordinated in a distorted tetra-hedral environment. The coordination of one Al atom includes three methyl-C atoms and the O atom from the ligand, whereas the second Al atom is surrounded by the O atom and one N atom from the ligand as well as by two methyl-C atoms. In the ligand, the dihedral angle between the tw...

In the title compound, C(8)H(7)N(5)O(2), the benzene ring makes a dihedral angle of 45.7 (2)° with the tetra-zole ring. In the crystal structure, the mol-ecules are linked into a chain running along the a axis by N-H⋯N hydrogen bonds, and the chains are linked through π-π inter-actions between the tetra-zole rings [centroid-centroid distance = 3.450 (2) Å].

The title compound, C(16)H(14)N(8), is a new chiral ligand designed for applications in supra-molecular chemistry and Fe(2+) spin-crossover complexes. The crystal structure shows a herring-bone arrangement of the mol-ecules, which are mutually linked via inter-molecular C-H⋯N inter-actions mainly donated by the alkyl and tetra-zole H atoms.

Fe(3)O(4) nanoprisms, synthesized by a solvothermal process, exhibited crystal plane dependent electrochemical activities, which opens an approach to nanoscale materials with controlled electrochemical properties.

The structure of the title compound, C7H4OS4, at 100 K has ortho-rhom-bic symmetry. In the crystal, tetra-thia-fulvalene mol-ecules form π-stacks along the a axis, with a stacking distance of 3.4736 (6) Å. Along the b axis, parallel stacks are inter-connected with each other through a network of weak C-H⋯O hydrogen bonds and short S⋯S contacts [3.4813 (7) Å]. Additional short S⋯S contacts [3.49...

The asymmetric unit of the title compound, C(8)H(14)N(6)O(2), contains two independent mol-ecules. In one mol-ecule, the amide-substituted N atoms of the tetra-zine ring deviate from the plane [maximum deviation = 0.028 (1) Å] through the four other atoms in the ring by 0.350 (2) and 0.344 (2) Å, forming a boat conformation, and the mean planes of the two carboxamide groups form dihedral angles...

The title chain polymer compound, [GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2)](n), was obtained in the reaction of GaBr(3) with Me(3)SiOLi in toluene/tetra-hydro-furan. The Ga(III) atom, located on a twofold rotation axis, is coordinated by four trimethyl-silanolate ligands and has a distorted tetra-hedral geometry. The Li(I) atom is four coordinated by one bridging Br atom located on an inversion...
