Homework Answers
This kind of bonding where
both pi and sigma bond reinforce each other is called Synergistic
bonding. Due to pi back bonding CO bond length increases and hence
bond will be weaker.

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...
