Dynamics of the electrochemical behavior of diimine tricarbonyl rhenium(I) complexes in strictly aprotic media

Article Abstract:

A study was conducted on the electrochemical properties of a family of mononuclear rhenium(I) (ReI) complexes. These are the [Re(super I)(CO)3LX]n. L in this equation is equal to pby, phen and X = Cl, CN (n=0). The metal-metal-bonded dimeric complexes [(L)-(CO3)3Re-Re(CO)3(L)], where L is equal to bpy, phen were examined in aprotic media. Two one-electron peaks were observed at the cyclic voltammetry curve relative to a 0.5 mM [Re(CO)3bpyCl]acetonitrile solution at 25 degrees Celsius. The solvent did not affect the peak I kinetics of both chloride and cyanide complexes.

A method for characterizing effective pore sizes of catalysts

Article Abstract:

A study was conducted to analyze a technique for preparing effective pore sizes of catalysts. The method supports an a priori description of relative pore sizes and can be utilized to examine different catalytic and absorbent systems. Molecular dimensions were determined using the Zindo molecular electronic structure programs. Results indicated the existence of the next effect that influences the shape selectivity of the exterior surface of the HZSM-5 structure.
