Molecular orbital analysis - d0 complexes

  1. Oct 16, 2011 #1
    1. The problem statement, all variables and given/known data

    I'm trying to perform a molecular orbital analysis of a tungsten hydride complex, (WH6) and I haven't been able to find an intuitive or basic definition for a "d0 complex". Every time I read an article about a d0 complex they tangentially mention them and then jump into the problem.

    2. Relevant equations

    What is the definition of a d0 complex?

    3. The attempt at a solution

    I thought it referred to any complex where the d orbital electrons do not directly participate in the bonding between the metal and its ligands. I just want a pure definition. Thank you so much.

    First, I think this post belongs rather to the Atomic and Molecular physics group.
    Then to your question: d0 means that the metal does not have d electrons in the given oxidation state. E.g. Tungsten is in the 6th subordinate group, hence in WH6 it is in oxidation state VI and has no d electrons.
