In this paper, we present the structural properties of middle graph of central graph of cycles $C_n$, star graphs $K_{1,n}$ and paths $P_n$ denoted by $M(C(C_n))$, $M(C(K_{1,n}))$ and $M(C(P_n))$ respectively. We mainly have our discussion on the harmonious chromatic number of $M(C(C_n))$, $M(C(K_{1,n}))$ and $M(C(P_n))$.
