The spin only magnetic moment of [MnBr_(4)]^(2)- is 5.9 BM. Predict the geometry of the complex ion. |
| Answer» Solution :Since the coordination number of `Mn^(2+)` ion in the complex is 4, it will be EITHER TETRAHEDRAL `(sp^(3))` or square planar `(dsp^(2))`. But the fact that magnetic MOMENT of the complex is 5.9 BM, it should be tetrahedral in shape rather than square planar because of the presence of FIVE UNPAIRED electrons in d-orbitals. | |
