Ok so i made a compund in a lab - Hexaamminenickel (II) terafluoroborate ( [Ni(NH₃)₆][BF₄]₂) from Nickel Chloride (NiCl₂) reacting with aqueous ammonia (NH₃) then with ammonium tetraflouroborate[NH₄][BF₄]. The intermediate being [Ni(NH₃)₆]Cl₂.

I need to write a balanced equation so i can calculate the percentage yeild of my product. Anyone able to help me??? I came up with NiCl₂ + NH₃ + (NH₄)(BF₄) = Ni(NH₃)₆(BF₄)₂ + Cl₂ but i dont think that is correct.

Write down a double replacement reaction (metathesis) between nickel chloride and ammonium tetrafluoroborate first, then form a complex. Finally add both reaction

 ;)this is reaction addition

thanks for the pointers.

I no this is from 2008 but I'm at uni and I just did this lab so Im posting the equation for other new students

[NA(NH3)6]Cl2 + 2NH4 + 2BF4 –> [Ni(NH3)](BF4)2 + 2Cl- + 2NH+4

voila

aren't there suppose to be six ammonia ligands in the complex?
