2-Mercaptopyrimidin-4-ol (2-thiouracil) complexes of copper(II), nickel(II), cobalt(II) and iron(III)

The complexes of 2-mercaptopyrimidin-4-ol with Cu11, Ni11, Co11 and Fe111 have been synthesized. Their structures have been assigned on the analytical, spectral (i.r, and visible), magnetic and d.t.a. data. It has been shown that there is a possibility of the Fe-O-Fe bond in the iron complex.
