Web5 aug. 2024 · A molecule of Co (CN) 3 (CI)3 exists as both a fac- and mer- isomer which both exhibit unique properties such as color and melting point. a. Draw the lewis structures for both the mer- and fac-isomers of Co(CN)3(CI)3 and label. Additionally identify and label if each structure is either achiral or chiral. b. Web1 mrt. 2024 · fac-isomer; mer-isomer; If we look closely at the mer-isomer, it has a plane of symmetry, so it is optically inactive. But the fac-isomer has no plane of symmetry. Still, it is optically inactive, why? Being a 12th grader, I wonder where am I wrong in my understanding of optical isomerism in coordination complexes.
WebA mixture of fac and mer [Co( β-diketonato) 3] will thus have four singlets for the methine hydrogen atoms and similarly the hydrogen atoms of the R and R' groups. Both the fac and mer isomers were observed on 1H NMR for [Co(tfba) 3] (2) and [Co(ba) 3] (3), with the mer isomer the main isomer. 3.2 Molecular structures Webi. Cis-fac isomer: Point Group D4h ii.

Web2 jul. 2004 · The spectra of PCl 4 F are best interpreted in terms of a C 3v structure in which the fluorine atom occupies an axial site; in PCl 3 F 2 (D 3h point group) the fluorine atoms also assume axial positions. For PCl 2 F 3, the symmetrical D 3h structure is shown to be incorrect. Available evidence supports the C 2v structure in which the fluorine atoms …
