On heating $\left[\mathrm{Mo}\left(\mathrm{N}_{2}\right)_{2}\left(\mathrm{PMe}_{2} \mathrm{Ph}\right)_{4}\right]$ and $\left[\mathrm{ReCl}\left(\mathrm{N}_{2}\right)\left(\mathrm{PMe}_{2} \mathrm{Ph}\right)_{4}\right]$, the products formed are respectively
(a)$\left[(\eta^{6}\text{-}\mathrm{PhPMe}_{2})\mathrm{Mo}(\mathrm{PMe}_{2}\mathrm{Ph})_{3}\right]$ and $\left[(\eta^{6}\text{-}\mathrm{PhPMe}_{2})\mathrm{Re}(\mathrm{PMe}_{2}\mathrm{Ph})_{3}\right]\mathrm{Cl}$
(b)$\left[(\mathrm{PMe}_{2}\mathrm{Ph})_{4}\mathrm{Mo}(\mu\text{-}\mathrm{N}_{2})_{2}\mathrm{Mo}(\mathrm{PMe}_{2}\mathrm{Ph})_{4}\right]$ and $\left[(\mathrm{PMe}_{2}\mathrm{Ph})_{4}\mathrm{Re}(\mu\text{-}\mathrm{Cl})_{2}\mathrm{Re}(\mathrm{PMe}_{2}\mathrm{Ph})_{4}\right]$
(c)$\left[(\eta^{6}\text{-}\mathrm{PhPMe}_{2})\mathrm{Mo}(\mathrm{PMe}_{2}\mathrm{Ph})_{3}\right]$ and $\left[(\mathrm{PMe}_{2}\mathrm{Ph})_{4}\mathrm{Re}(\mu\text{-}\mathrm{Cl})_{2}\mathrm{Re}(\mathrm{PMe}_{2}\mathrm{Ph})_{4}\right]$
(d)$\left[(\mathrm{PMe}_{2}\mathrm{Ph})_{4}\mathrm{Mo}(\mu\text{-}\mathrm{N}_{2})_{2}\mathrm{Mo}(\mathrm{PMe}_{2}\mathrm{Ph})_{4}\right]$ and $\left[(\eta^{6}\text{-}\mathrm{PhPMe}_{2})\mathrm{Re}(\mathrm{PMe}_{2}\mathrm{Ph})_{3}\right]\mathrm{Cl}$
