The magnetic moment for two complexes of empirical formula Ni(NH3)4 (NO3)2.2H2O is zero and 2.84 BM repectively. The second complex is not a neutral complex. The correct formula and geometry of the first complex is : |
(1) | [Ni(H2O)2(NO3)2].4NO3 = Tetrahedral |
(2) | [Ni(NH3)4] (NO3)2.2H2O = Tetrahedral |
(3) | [Ni(NH3)4](NO3)2.2H2O = Square planar |
(4) | [Ni(NH3)4(H2O)2](NO3)2 = Octahedral |
