Reaction of nitrosyltetrafluoroborate to Vaska's complex gives complex A with angle $\mathrm{M}-\mathrm{NO}=124^{\circ}$. The complex A and its N-O stretching frequency are, respectively
(a)$\left[\mathrm{IrCl}(\mathrm{CO})(\mathrm{NO})\left(\mathrm{PPh}_{3}\right)_{2}\right] \mathrm{BF}_{4}, 1620 \mathrm{cm}^{-1}$
(b)$\left[\mathrm{IrCl}(\mathrm{CO})(\mathrm{NO})_{2}\left(\mathrm{PPh}_{3}\right)\right]\left(\mathrm{BF}_{4}\right)_{2}, 1730\ \mathrm{cm}^{-1}$
(c)$\left[\mathrm{IrCl}(\mathrm{CO})(\mathrm{NO})_{2}\left(\mathrm{PPh}_{3}\right)\right]\left(\mathrm{BF}_{4}\right)_{2} 1520 \mathrm{cm}^{-1}$
(d)$\left[\mathrm{IrCl}(\mathrm{CO})(\mathrm{NO})\left(\mathrm{PPh}_{3}\right)_{2}\right], 1820\ \mathrm{cm}^{-1}$
