Question
Write down the IUPAC name of the following complex and indicate the oxidation state, electronic configuration and coordination number. Also, give the stereochemistry and magnetic moment of the complex:
K[Cr(H2O)2(C2O4)2].3H2O
Solution
| IUPAC name of the hybrid compound | Oxidation state of the central metal | Coordination number | Shape | Central metal ion | Electronic configuration | The value of n and the magnetic moment |
| Potassium diaquadioxalatochromate(III) hydrate | −1 + x + 2 × (0) + 2 × (−2) = 0 ∴ x = +3 |
6 | Octahedral | Cr3+ |
3d3, \[\ce{t^3_{2g}e^0_g}\] |
n = 3, `sqrt(3(3 + 2))` = 3.87 BM |
