Answer:
The other geometry is square planar and this is because the four coordinate complexes forms d⁸ configuration.
Explanation:
(1) The other geometry is square planar
(2) This absorption spectrum (square planar) strongly suggests a tetrahedral geometry because in the molecular geometry, a central atom is surrounded by constituent atoms, which form the corners of a square on the same plane.
This square planar is as a results of d⁸ electronic configuration and this is common for transition metal complexes with d⁸ configuration.
