Abstract
Complexes of
3-mercapto-1,3-diphenylprop-2-en-1-one, PhC(SH)=CHCOPh, with iron(III), cobalt(III), rhodium(III),
nickel(II), palladium(II), platinum(II), copper(II), silver(I), zinc(II), cadmium(II), and
mercury(II) have been prepared and characterized. Complexes of 4- mercaptopent-3-en-2-one, MeC(SH)=CHCOMe, with cobalt(III) and cadmium(II) and of ethyl
thioacetoacetate, MeC(SH)=CHCOOEt,
with cobalt(III) and copper(I) are also reported.
The infrared spectra of the complexes of
3-mercapto-1,3- diphenylprop-2-en-1-one are discussed. The similarity of the
spectra of the silver(I), cadmium(II),
and mercury(II) complexes to those of the free ligand and its S-methyl
derivative, PhC(SMe)=CHCOPh, indicate that in these three complexes the carbonyl
oxygen of the ligand is not, or is at most weakly, coordinated to the metal
ion. The assignments of the principal bands in the other metal complexes of
this ligand are: 1550- 1525 cm-1, v(C-C); 1480-1458 cm-1,
v(C=O); 1438-1412 cm-1, v(C=O)+δ(C-H); 1270-1260 cm-1,
v(C--S); 498-437 cm-1, v(M-O); 399-376 cm-1, v(M-S).
