In the title inclusion compound, C(26)H(26)N(4)O(6)·C(2)H(4)Cl(2), the solvent mol-ecule occupies a cavity inside the clip-type mol-ecule which is based on the glycoluril skeleton with two ethyl acetate substituents on the convex face of the glycoluril system. The dihedral angle between the aromatic rings of the host is 43.59 (4)° and the centroid-centroid distance is 6.741 (5) Å. The 1,2-dichl...

By using quantum mechanical DFT calculations, the most probable structure of the bambus[6]uril x NO3(-) anionic complex species was derived. In this complex having C3 symmetry, the nitrate anion NO3(-), included in the macrocyclic cavity, is bound by twelve weak hydrogen bonds between methine hydrogen atoms on the convex face of glycoluril units and the considered NO3(-) ion.

Four complementary hydrogen bonds between sulfamides and ureas link adjacent hydrogen-bonded ribbons to form sheets in the solid-state; this interaction is investigated in solution using model urea and sulfamide compounds.

Glycoluril derivative--whose bulky Ph-C[triple bond]C- substituents prevent formation of H-bonded tapes--undergoes solvent dependent assembly in the crystal; a tetrameric molecular bowl is formed by R(24) H-bonding interactions from CH(2)Cl(2) whereas DMF results in H-bond dimerization followed by oligomerization via C-H...pi interactions.

the kinetics of catalyst deactivation and coke formation during dehydrogenation of propane over supported pt–based catalysts and, in particular, the effect of alkali metal promoters on catalyst activity and stability were studied. the analysis of propane conversion data showed that there is an optimum level of alkali metal promoter loading for both catalyst activity and stability.a model based ...

The present study deals with analysis of the activity of catalysts prepared by addition of different metals to Copper and Cobalt based catalysts for CO oxidation and the variation in activity caused by changes in composition. A series of catalysts were prepared with Cu:Co molar ratio 1:4 and a third metal (M= Ce, Ni, Au, Mg) was added in three different quantities. Compositions were prepared by...
