The complex is paramagnetic

The complex is an outer orbital complex

The complex gives white precipitate with silver nitrate solution

The complex involves d²sp³ hybridization and is octahedral in shape.

All the members exhibit +3 oxidation state

Because of similar properties the separation of lanthanoids is not easy.

Availability of 4f electrons results in the formation of compounds in +4 state for all the members of the series.

There is a gradual decrease in the radii of the members with increasing atomic number in the series.
