Question

What kinds of titanium complexes can be made?

Answer 1

Some straightforward examples are `"TiCl"_4` (tetrachlorotitanium(IV)) and `["Ti"("CO")_6]^(2-)` (hexacarbonyltitanate(II)). The former has a `+IV` oxidation state on titanium, and the latter has a `-II` oxidation state. These you might be able to imagine. The former is tetrahedral, and the latter is octahedral.

A cool example is the double decker titanium sandwich shown below (yum!):

There are of course many others, but these are just a few.
