I suggest reagent grade ammonia (ammonium hydroxide).  also, it might be nice
to wash the stuff in ether ... but beware of the ether fumes!  ether is
very volatile (though NOT NEARLY as volatile as NI3!) besides being
carcinogenic.  NI3 has a highly unstable crystaline structure so it undergoes
decomposition when dry.  Hydronium ions in water also tend to cause the
stuff to decompose. Though not recommended (you should use it when you make
it!) it is possible to keep NI3 "wet" in certain solvents without it blowing
up.  What is important is to not have it dry on any part of a container.
