Formula Unicode styled:
[Ho(OH₂)({C₅H₄Me}₃)]
Compound name(s):
Aqua-tris(η⁵-methylcyclopentadienyl)-holmium
Central atom:
Charge on formula unit (QN):
0
Attached groups:
Compound type:
Notes:
The three cyclopentadienyl groups as a set contribute 13 electrons rather than 15 (five for each cyclopentadienyl) to the metal. This is because one of the ligand orbitals set associated with the three cyclopentadienyl groups has no symmetry match with relevant metal atomic orbitals. This reduces the formal metal electron count by two. See:
