The electronic configuration of \(Co ^{3+}\) ion
\(=[A r]_{18} 3 d^{6}\)
The splitting in octahedral field is shown below
\(C o^{3+}=3 d^{6}\left(\right.\) or \(\left.t_{2 g}^{6} e_{g}\right)\)
\(\therefore\) There is no unpaired electron, so it is diamagnetic in nature.
$(1)$ ટ્રાન્સ $-[Co(NH_3)_4 Cl_2]^+$
$(2)$ સિસ $-[Co(NH_3)_2 (en)_2]^{3+}$
$(3)$ ટ્રાન્સ $-[Co(NH_3)_2(en)_2]^{3+}$
$(4)$ $NiCl^{2-}_4$
$(5)$ $TiF^{2-}_6$
$(6)\, CoF^{3-}_6$
