| Popis: | The complexes Fe(pyrazole)3Cl3, Fe(3-methylpyrazole)3Cl3, Fe(py)4Cl3, Fe(pyrimidine)2Cl3, and Fe(pyrazine)5/2Cl3 have been prepared; the vibrational spectra of these and a number of similar, indium complexes have been recorded and metal–nitrogen and metal–halogen vibrational modes assigned. The e.p.r. spectra of some of the complexes are discussed and the results compared with the predictions of the vibrational spectra. The co-ordinating ability of a number of ligands is rationalised in terms of pKa and steric effects. |
