What is an example of a tetragonal molecule with sigma donor only ligands?
[Zn(NH3)4] 2+ is an example of a tetragonal molecule with sigma donor only ligands.
In this complex, NH3 is a sigma donor ligand only and molecule possesses tetragonal geometry.
What is an example of a tetragonal molecule with sigma donor only ligands?
1)Please explain backbonding with LFT (Use MO diagram) and explain pi donor sigma donor pi acceptor by MO diagram 2) Are sigma donors included in all ligands? => strength of ligands :pi donor(with sigma donor) < sigma donor < pi acceptor(with sigma donoor)
Classify the following species as T-donor,-only, or TT-acceptor ligands. TT Donor ? Only IT Acceptor
Classify the following species as ? -donor, ?-only, or ?
-acceptor ligands.
can some one explain the donor abilitity of the ligands , what
if CN was introduced, what rank would it be?
a) Circle the phosphine with the strongest ability to act as a sigma-bond donor PPh3 PC13 PEt3
4.) Square planar metal complexes (MLA) are an extreme case of tetragonal elongation, where the metal-ligands bonds along the z axis of an octahedral complex are stretched until the ligands are completely removed from the metal complex. Using the octahedral crystal field below as a starting point, show how the orbital splitting changes upon elongation of the M-L bonds along the z-axis until the two axial ligands are removed. Label all orbitals and use dashed guidelines to show how individual...

1) Consider the molecule [Nicl]. It is tetrahedral geometry and Ta symmetry Consider the sigma-bonding and determine a reducible representation for the molecule. Determine the irreducible representation. Draw a qualitative molecular orbital diagram with electrons and symmetry labels. Consider carefully the oxidation state of the metal and ligands and fill in electrons thoughtfully. You will only utilize the 3d orbitals on Nickel, not the 4s or 4p. The ligand group orbitals of the chlorine ligands should be lower in energy...

1. Tetragonal Crystal System (a) What are the defining conditions for the 3D tetragonal crystal system in terms of a b, c and a, ß,y? (b) What are the possible Bravais lattices for the tetragonal crystal system? (c) Show using diagrams how the missing special positions are composed of simpler unit cells with a smaller volume (same question as discussion #1). (d) For the cases shown in (c), what are the lattice parameters of the new, simpler unit...
A molecule or on that donates the hydrogen in a hydrogen bond is a hydrogen bond donor A molecule or son that binds to this hydrogen is a hydrogen bond acceptor. Specify the hydrogen bonding behavior of the 4 species below by selecting: donor for species that act as donors only acceptor for species that act as acceptors only both for species that act as both donors and acceptors neither for species that act neither as donors nor as acceptors....
