Complex	EC	Unpaired electrons
$(1) {[Fe (en) (bpy) {({NH}_{3})}_{2}]}^{2 *}$	${Fe}^{2 +} = 3 d^{6} = t_{2 g^{2, 2, 2}}, e_{g}^{0.0}$	$0$
$(2) [Pd (gly)_{2}]$	${Pd}^{2 +} = 4 d^{8}$	$0$
$(3) {[Ti {({NH}_{3})}_{6}]}^{3 +}$	$T_{i 3}^{3} = 3 d^{1}$	$1$
$(4) {[Co (OX)_{2} (OH)_{2}]}^{-} (Δ_{0} > P)$	${Co}^{5 +} \Rightarrow 3 d^{4} \Rightarrow t_{2 g^{2, 1, 1}}, e_{9}^{0, 0}$	$2$
