Give the formula of the following coordination entities :
(b) `Ni^(2+)` ion is bound to two water molecules and two oxalate ions. Write the name and magnetic behaviour of each of the above coordination entities.

Text Solution

Verified by Experts

`[Ni(C_(2)O_(4))_(2)(H_(2)O)_(2)]^(2-)` : diaquadioxalatonickelate (II) ion.

Nickel undergoes `sp^(3)d^(2)` hybridisation. There are two unpaired electrons. Hence, the complex is paramagnetic in nature with a magnetic moment of 2.83 BM.
