The metal complex that exhibits a triplet as well as doublet in its ${}^{31}\mathrm{P}$ NMR spectrum is

(a)mer-$[\mathrm{IrCl_3(PPh_3)_3}]$

(b)trans-$[\mathrm{IrCI(Co)(PPh_3)_2}]$

(c)fac-$[\mathrm{IrCl_3(PPh_3)_3}]$

(d)$[\mathrm{Ir(PPh_3)_4}]^{+}$

Answer

Answer: A ✓ checked by 4AB · confidence high
