Red precipitate is obtained when ethanol solution of dimethylglyoxime (DMG) is added to ammoniacal $\text{Ni(II)}$. Which of the following statements is NOT true?

When ${\text{Ni}}^{2+}$ reacts with $\text{DMG}$ in basic medium, a rosy-red precipitate of $[{\text{Ni(DMG)}}_2]$ is formed.DMG acts as a bidentate ligand.The central ${\text{Ni}}^{2+}$ ion ($d^8$) undergoes $ds{p}^2$ hybridization, resulting in a square planar geometry.The complex is stabilized by intramolecular hydrogen bonding.Therefore, the statement that it has a tetrahedral geometry is false.
