Exact formula of tetra-amine-zinc complex

  1. Feb 3, 2012 #1
    Sorry this post doesn't look beautifulized and pretty; its 23.00 here.

    When ammonia is added to hexaaquazinc ions, the NH3 acts as a base and forms [Zn(H2O)4(OH)2], better known as Zinc hydroxide. However, in excess NH3, the ppt will redissolve as a tetraaminezinc complex. My question is: is the precise formula [Zn(NH3)4]2+ or [Zn(NH3)4(H2O)2]2+???
    Trivial, I know, but I cannot rest until this itch is scratched. Logic would suggest the latter, but a lot of sites seem to quote the former. If there are no stray water ligands, what is the reason for this?

    Thanks in advance.:bugeye:

    Edit: Grr... Hate these constantly reappearing templates.
