Draw an MO diagram for the [FeH6]2- complex. Sketch the group orbitals of the 6 H ligands and show how they overlap wi...
We have covered the MO diagram for a general ML6 (On point group) complex with o only ligands. a. Without looking at your notes, draw this MO diagram. b. Repeat this process for an ML4 (Ta point group) complex. You will not have to derive a full Oh or Ta MO diagram on the exams, but please try to understand the steps.
4. A low oxidation state organometallic complex contains -acceptor ligands and the metal center tends to acquire 18 electrons in its valence shell, thus filling the valence orbitals. This is known as the 18-electron rule. Show that Mo(CO)6 obeys the 18-electron rule.
[Co(NH3)6]3+ion4. Construct the MO diagram. Label all atomic, group and molecular orbitals with symmetry labels. Fill in the diagram with the appropriate number of electrons. Assume that this complex is a strong field, low spin complex.5. a) What set of orbitals is the HOMO (highest occupied molecular orbitals).b) Is this set of orbitals classified as bonding, antibonding or non-bonding (no symmetry match)?6. What set of orbitals is the LUMO (lowest unoccupied molecular orbitals)?
13. (14 pts) MO Theory Draw the complete (core and valence) molecular orbital energy level diagram for the homonuclear diatomic molecule Be2. Use standard MO symbols to label the energy levels (That is: o, o, , or n*, as needed, with subscripts indicating which atomic orbitals formed them.) a. Sketch the molecular orbital formed when two 2p orbitals, one each on each Be atom, overlap to form a o antibonding MO b. Using your MO energy level diagram in (a),...
Assuming that only the valence orbitals are involved in bonding, draw an approximate MO energy-level diagram describing the relative energies of these eight molecular orbitals in N2. What is the apparent bond order for N2? Are there any unpaired electrons in this molecule? If so, how many? (Have all small details sigma,pi etc)
Draw just the homonuclear diatomic MO diagram through the d - orbitals. Then draw in the electrons for KK(4s)2(3d)2
Sketch the MO diagram of CO using only the 2s and 2p orbitals for i) no sp-mixing, ii) strong sp-mixing. Assign the correct representations to each MO. How many peaks with vibrational fine structure do you expect in an experimental photoelectron spectrum? 1 7 5 3
i can't solve this question of coordination chemistry, could someone hlep me please Exercise 1: 1. What kind(s) of interaction between the ligand and the metal ion is(are) considered in the crystal field approach? 2. Give and justify the degeneracy lifting for a tetrahedral complex. Would it be the same for an octahedral complex? 3. Let us consider hexaaquacopper(II) ion. Justify the elongation of two opposite Cu-O bonds (along z for example) compared to the other four Cu-O bonds using...
In addition to interacting with s and p orbitals of ligands such as NH,, CN, etc., d orbitals can also interact with other d-orbitals, resulting in the formation of metal-metal bonds. Thus, for a simple metal dimer (i.e., ignoring any other ligands), we can envision the following interactions: M1M2 ? bond bond 8 bond where the o bond represents a face-to-face interaction between the two d orbitals. Considering only the d orbitals on each metal and taking the metal-metal bond...
#8 Sketch a qualitative atomic orbital energy-level diagram for all of the electron and orbitals of Fe and Fe^2+. Label all of the orbitals. Draw structures and calculate the formal charge on the nitrogen atom in NH_3, N_2H_4, and NH^-1_2.
