Hi, I have been asked to provide both an ionic and covalent electron count for VO(acac)2 but I am doubtful that my answers are correct..
Ionic method:
V(IV) - d1 - 1 electron
Oxo ligand (O2-) 4 electrons
2 X acac (2x4) 8 electrons
= 13e-
Covalent method
V - d5 - 5 electrons
Oxo ligand - 2 electrons
2 x acac (2x3???) 6 electrons
= 13e-
Surely this isn't right....
