The title compound has been prepared and characterized by EA, IR and TG. The crystal structure of tris-(4-morpholinecarbodithioato-S, S')iron(ni), FeCSjCNQHgO^i was determined by X-ray diffraction analysis. It crystallizes in triclim'c system, space group P-l, with lattice parameters a = 0.9300(2) nm, b = 1.0490(2) nm, c = 1.3710(3) ran, a = 100.60(3)°, /? = 95.40(3)°, y= 106.60(3)°, 7=1.2445(4) nm3, Mr = 542.58, Z = 2. In the structure, central Fe atom coordination geometry is distorted octahedron with the six'S atoms from three bidentate [SjCNG^HgO] ligands. The octahedron is distorted as a result of forced configuration of the four-membered chelate ring. The six Fe- S bond distances are in the range of 0.2423(5) ~ 0.2458(2) nm. The IR spectral data are in agreement with the structural data. The TG data indicate that it decomposed completely at the 791.80 °C .
