Several complexes of N,N′‐diethylthiourea (Dietu) with zinc(II), cadmium(II) and mercury(II) halides were prepared and characterized by i.r. (4000–60 cm −1 ), raman (400–60 cm −1 ), in the solid state and n.m.r. and conductometric methods in solution. The complexes Zn(Dietu) 2 X 2 , Cd(Dietu) 2 X 2 (X Cl, Br, I) and Hg(Dietu) 2 X 2 (X Br, I) are tetrahedral species in which intramolecular NH … X interactions have been observed. The 1:1 mercury(II) complexes, Hg(Dietu)X 2 (X Cl, Br), appear to have a dimeric tetrahedral halide‐bridged structure in the solid state. In all these complexes N,N′‐diethylthiourea is sulphur‐bonded to the metal.
