Question

Which of the following statement is correct for the complex `Ca_(2)[Fe(CN)_(5)O_(2)]` having `t_(2g)^(6),e_(g)^(0)` electronic configuration ? .
A. `d^(2)sp^(3)` hybridised and diamagnetic
B. `sp^(3)d^(2)` hybridised and paramagnetic
C. `sp^(3)d^(2)` hybridised and diamagnetic
D. `d^(2)sp^(3)` hybridised and paramagnetic

Answer 1

Correct Answer - D

Complex is paramagnetic due to presence of unpaired electron at `(O_(2) Θ)` I .e superoxide acting as ligand .
