anhydrous calcium chloride is a common drying agent due to its hygroscopic nature, but my in my textbook said CaCl2 cannot dry ammonia gas becoz of formation of additional product

CaCl2 + 2NH3 + 2H2O ↔ Ca(OH)2 + 2NH4Cl

Also, in the same way that water forms a hydrate, NH3 forms an ammine. (Does the book say "additional" or "addition"?)

does that mean formation of calcium complex ion? with NH3 as ligand?

I know it's an old post, but it usually is shown as google results searching this subject.

If useful to someone, this man had no problem at all mixing calcium chloride and ammonia...
