| 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+ |

Magnetic moment of \[\ce{[MnCl4]^{2-}}\] is 5.92 BM. Explain giving reason.
Explain why \[\ce{[Fe(H2O)6]^{3+}}\] has magnetic moment value of 5.92 BM whereas \[\ce{[Fe(CN)6]^{3-}}\] – has a value of only 1.74 BM.
Assertion: \[\ce{[Fe(CN)6]^{3-}}\] ion shows magnetic moment corresponding to two unpaired electrons.
Reason: Because it has d2sp3 type hybridisation.
The correct order of magnetic moment (spin only value in B.m.) is:
Low oxidation state of metals in their complexes are common when ligands ______.
