Dear Hussein, thank you for posting this question on RG. However, it would be very helpful if you could be a bit more specific. It is not quite clear to me what you mean by "evaluate the metal ions". Please specify! For example, you can determine the metal content of newly prepared metal complexes by elemental analysis. In some cases you can also detect the metals directly by metal-specific NMR spectroscopy, e.g. in the case of the nucleus 195Pt (cf. https://en.wikipedia.org/wiki/Platinum-195_nuclear_magnetic_resonance). Yet another potentially helpful option would be the characterization of your complexes through was spectrometry. It just depends on what kind of instruments you have available at your institution.

When it comes to publication of new coordination compounds, most journals require the "usual set" of analytical and spectroscopic methods for full characterization of the complexes. This includes elemental analysis as well as FTIR, NMR, MS and ideally a single-crystal X-ray structure determination.

Good luck with your work and best wishes, Frank Edelmann

Dear Hussein Ali Kadhim Kyhoiesh

Many thanks for your questioning. In case of quantitative estimation of metal/metal ions in the synthesized complex may be determined by elemental analysis as mentioned by Frank T. Edelmann . However, if you want to detect metal/metal ion in a complex you can use atomic absorption spectroscopy and NMR spectroscopy for some NMR active metals. On the other hand if want to know whether the complex is formed or not, you can take the PMR or even IR spectra for the prepared compound and that of the uncoordinated ligand, and finally match the spectra.

Good luck with your work.

Hi Hussein Ali Kadhim Kyhoiesh . You have different techniques to identify the metals in the complexes . One good technique is ES-MS/MS technique . See the following useful link: https://www.nature.com/articles/srep26785
