2-imino-4-oxo-1,3-thiazolidine complexes of silver(I), zinc(II), cadmium(II) and mercury(II)

Complexes of the types [MXL2], [MXL2L2] and [MX2L] (where M = AgI, ZNII, CdII or HgII; X =Cl, Br, I, SCN, NO3, ClO4 or 1 2SO4; L =2-imino-4-oxo-1,3-thiazolidine) have been prepared as white, diamagnetic non-electrolyte compounds. The infrared spectral studies suggest that silver and zinc derivatives are N-bonded, cadmium complex is S-bonded and mercury derivatives are both N- and S-bonded. © 1975.
