Could someone show me cytosine and thymine bonded together with a phosphodiester bond

I can't seem to find an example. An explanation will work too.

Thanks

(Sorry for the long link)

The phosphodiester bond is just the bond between the phosphate group and the sugar (either deoxyribose or ribose) in the backbone of the DNA or RNA. This picture is a great example of this,
