Abstract New complexes of allylpyrazole with metal ions have been prepared and characterized. The ir spectra of the monovalent metal complexes (Cu(I) and Ag(I)) indicate that the ligand is coordinated through both the pyrazolyl nitrogen and the olefinic group whereas divalent metal halides (Co(II), Cu(II) and Zn(II)) form 1 : 2 adducts with the ligand, in which only pyrazolyl nitrogen coordinates to the metal ion and the olefinic group is free. Cupric bromide reacts with allyl-dimethylpyrazole… CONTINUE READING
