Rhenium complexes configuration

Ma et al. also studied PVK-based PPLEDs using rhenium complex in [28,51], They have prepared the PPLED in configuration ITO/PVK bpyRe (27) DCM (28)/Al (DCM is 4-(dicyanomethylene)-2-methyl-6-[p-(dimethylamino)styryl]-4//-pyran), where the bpyRe... 

Rhenium complexes containing the metal in the oxidation state +III are comparatively numerous. This may be ascribed to the fact that the d configuration of the rhenium center can readily be stabilized by ligands with pronounced donor and rr-acceptor properties. Most of the rhenium(III) compounds are stable against hydrolysis rendering them suitable for nuclear medical applications. 

Consider the compounds of a given metal such as rhenium. Then consider a three-dimensional matrix with the three independent, discrete variables electronic configuration E)y coordination number (C), and ionic charge (Q) corresponding to the three dimensions. The known rhenium complexes can be placed in this matrix in the appropriate cells corre-... 

Gladysz has investigated the solution behaviour and configurational stability of these chiral rhenium complexes further, he extensively studied the chiral recognition process that results from the enantioface binding of alkenes, aldehydes and ketones on these rhenium chiral Lewis acids 3.7 and/or 3.8. There is a huge body of papers and reviews on this chemistry, and the reader may consult the referenced review. ... 

Glaser oxidative coupling [Cu(OAc)2/py] of the rhenium ethynyls Re(C=CH)(NO)(PR3)Cp (R = Ph 248-250 tol, C6H4Bu -4251) affords the corresponding diyndiyls Re(NO)(PR3)Cp 2(p-C=CC=C) (96) as diaste-reotopic mixtures. Fractional crystallization leads to diastereotopic enrichment, or resolution for R = Ph, which permitted cystallographic assignment of the configuration. 13C-Labeled complexes were prepared and... 

Hexacoordinate species (C = 6) with the rare gas configuration E = 18) are particularly favored. Therefore, in the CEQ-msitrix the row corresponding to C = 6 and the column corresponding to F = 18 are outlined in double lines. In the rhenium C /Q-matrix (Table I), as well as the other Ci/Q-matrices given in this paper (Tables II to VII), the complex types are concentrated along the C = 6 row and the = 18 column.
