Vedclass · Answer

(B) Zeise's salt is $K[PtCl_3(\eta^2-C_2H_4)]$. In this organometallic complex,the ethylene ligand $(C_2H_4)$ acts as a $\sigma$-donor by donating electron density from its $\pi$-orbital to an empty $d$-orbital of the $Pt^{2+}$ metal center. Simultaneously,the metal center acts as a $\pi$-donor by back-donating electron density from its filled $d$-orbital into the empty $\pi^*$-antibonding orbital of the ethylene ligand,making the ethylene ligand a $\pi$-acceptor. Therefore,the metal center acts as a $\sigma$-acceptor (receiving $\sigma$-donation) and a $\pi$-donor (providing $\pi$-back-donation). However,in the context of the ligand-metal interaction description,the metal center is characterized by its ability to accept $\sigma$-electrons and donate $\pi$-electrons.

In Zeise's salt,the central metal atom acts as:
