The electronic spectra of 3-mercapto-1,3-diphenylprop-2-en-1-one, PhC(SH)=CHCOPh, and its zinc(II), silver(I), cadmium(II), mercury(II), and S-methyl derivatives are given and some provisional assignments of the bands are made. The spectra indicate that the oxygen atom of the ligand is weakly coordinated in the silver and cadmium complexes and that in the mercury complex the ligand is coordinated through the sulphur atom only. The spectra of two other monothio-β-diketones, R1C(SH)=CHCOR2 (R1 = R2 = Me, But), are also given. The spectra of the nickel(II) chelates of seven monothio-β- diketones are discussed and the bands are assigned as metal d-d, metal- to-ligand, ligand-to-metal, and ligand-to-ligand transitions.
