The [Co(H2O)6]2+ Cation Do you expect this complex ion to have a Jahn-Teller Distortion? Explain why or why not. To simplify: Reference: CSD Code: AJIDON W. Zhang, Y.T. Chen. Acta Crystallogr., Sect E: Struct. Rep. Online, Vol 65 p m1548, 2009 R = 2.52 The reported average uncertainty in (C-C) bond lengths range from 0.001 to 0.005 Å And note, there are no C-C bonds in this complex ion however the ion co-crystallized with a anion having C-C bonds Does this molecule exhibit a Jahn-Teller Distortion? Be sure to note if the relevant bond lengths you are comparing either fall within experimental error of each other or are different enough outside of the experimental error to justify your answers in all answers To determine bond lengths: You can either click (some platforms you need to right click) on the Jsmol icon and choose Measurements You can use the tools provided such as "Display Measurements" You can also choose if your distances are reported in Angstroms, nanometers or picometers We have found we obtain the highest number of significant figures if we measure in picometers |
