  Using \textit{ab-initio} methods we study structural, electronic and magnetic
properties of two dimensional compounds with stoichiometry M$_2$N$_3$ (M-metal,
N=S,Se,Te). Our study shows that structures with Cr, Ti, and Mn are stable,
with significant binding energy. Also, such structures are semiconductors with
narrow band gaps. We also show that Cr$_2$Se$_3$, Cr$_2$Te$_3$ and Mn$_2$Te$_3$
have considerable magnetic moments. The negative values of magnetic anisotropy
energy suggest, that these materials can maintain ferromagnetic ordering in
non-zero temperatures with estimated Curie temperatures in the range of 30-55
K.
