Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis configuration, the two chloride ligands are adjacent to each other. The other isomer...
optical stereoisomerismSome peculiarities of the effect of enantiomers of the monodentate ligand on the stereoisomerism of the mixed octahedral tetrafluoride complexes of d(0)-transition metals are established by the F-19{H-1} and (31)?{H-1} NMR methods for the complex formation of TiF4 ...

422, 520 and 576 nm (shoulder), whereasAg22has absorptions at 354, 437, 505 and 582 nm (Fig.1c). In detail, the absorption peak inAg21at 422 nm red shifts to 437 nm, while, the peak at 520 nm blue shifts to 505 nm inAg22...
These four isomers represent the basic cis-尾 and trans geometries which additionally display a secondary isomerism due to the meso and racemic configurations of the inner nitrogen atoms. Most of the complexes were of the type trans-R,R:S,S-[Co-(3,2,3-tet)XY] n+, where X and Y ...
In future work, we will calculate the stability of the two complexes in the crystal lattice in more detail using density functional theory (DFT) methods. 2.4. Infrared and Raman Spectroscopy The asymmetric and symmetric H–C vibrations of the CH3 and CH groups of both com- plexes were ...
