In class we recently discussed how to draw out molecular orbital energy diagrams for compounds such as NH3 (ammonia). Building upon this, we touched on how to construct a molecular energy diagram for ML6 type coordinate complexes, namely [Cr[NH3]6)3+. I am confused as to where to begin our diagram formation. All I know right now is that we consider that NH3 coordinates to Cr through it's a1 HOMO. I don't know how to proceed beyond this.

    $\begingroup$ Have you tried looking in a textbook? Because of the importance of octahedral complexes, all inorganic texts devote a fair amount of space to construction of MO diagrams for ML6 complexes. $\endgroup$ – orthocresol Mar 14 '19 at 23:15
  • $\begingroup$ Unfortunately our prof doesn't have a textbook for us in this class. We're only left to our handwritten notes. $\endgroup$ – Hen ro Mar 14 '19 at 23:43

  • $\begingroup$ @Henro You can literally open any textbook about inorganic chemistry... $\endgroup$ – Greg Mar 15 '19 at 3:33
