Name one ion whose central atom has `sp^3 d^3` type of hybrid orbitals.

Explanation

To solve the question of naming one ion whose central atom has `sp^3 d^3` hybrid orbitals, we can follow these steps:

### Step 1: Identify the Hybridization Type
The hybridization `sp^3 d^3` indicates that the central atom is using one s orbital, three p orbitals, and three d orbitals to form hybrid orbitals. This type of hybridization typically occurs in octahedral complexes with one lone pair of electrons.

**Hint:** Remember that `sp^3 d^3` hybridization usually corresponds to a central atom with a coordination number of 6, where one of the positions is occupied by a lone pair.
