Naming binary compounds * 2?

Question

Name each of the following compounds.

(a) PI3

(b) ICl3

Answer 1

If PI3 is meant to be one phosphorus and three iodines:

Phosphorus triiodide

ICl3 is physically impossible if I is iodine, so I have no clue how to answer that one. Repost with a correction and then I can help you.

For future notice, to write chemical compounds on here, use the following notation:

PCl(3)

The parenthesis denote the subscript that isn't supported in plain text.
