Draw the d-orbital energy diagram for a square planar complex [M(L)4]2+. Draw a schematic representation (i.e. simple 2D picture) of the metal-ligand antibonding orbital that corresponds to the highest energy orbital of the splitting diagram. How is this square planar splitting diagram related to the d-orbital splitting diagram for a Jahn-Teller distorted octahedral complex?

The molecular orbital diagrams of hydrogen and helium can tell us a lot about how these elements interact and behave. The MO diagram for H2 is below. Before bonding, each neutral hydrogen atom contains one electron in a 1s orbital. The in-phase overlap of these orbitals generates Select a sigma bonding orbital that is lower in energy than an H 1s orbital a sigma bonding orbital that is higher in energy than an H 1s orbital a pi bonding orbital...

In 1984, the first organometallic compounds with H2 as an ?2 ligand were synthesized: M(CO)3(PR3)2(H2) with M = Mo or W and R = cyclohexyl or isopropyl. These complexes illustrate back-bonding with H2 as a ligand. a. Draw a structure for this molecule (just use R for the substituents on the P atoms). Because the R groups are very bulky, assume that the two PR3 ligands are in a trans configuration. Only one isomer is then possible. Show that this...

Band theory is an extension of molecular orbital theory. According to band theory, atomic orbitals between atoms in a sample form a nearly continuous band of molecular orbitals. In a metal, the bottom half of the band is composed of bonding molecular orbitals and the top half of the band Is composed of anti-bonding molecular orbitals. Transition metals from the 4th period have a band of molecular orbitals formed from a composite of 4s and 3d orbitals. Metallic properties, including...
