Explanation:
The given compound is a coordination compound having coordinate bonds between the metal and the ligand.

We know,
the geometry corresponding to d2sp3 is octahedral thus, the structure of the complex is octahedral.
Since, all of the 6e- get paired, there are no unpaired electrons and hence the complex is diamagnetic.
Final Answer:
The given complex is diamagnetic in nature and has an octahedral structure.
