Hi!
I have to prove that [RuO3(OH)2]2- is a paramagnetic compound, while [OsO2(OH)4]2- is diamagnetic. I applied the crystal field theory: ok, for the octhaedral compound, a Jahn-Teller distortion occurs, the degeneracy is lowered and the electrons couple( in dxy orbital). But I don't understand how I can apply the CF theory to Ru complex, which is not Oh or Td. How can I find the d orbitals energetical distribution for, say, a NC=5 complex ( I think its geometry is trigonal bipiramid)
Any ideas?
