The researchers compared several complexes to determine which one best facilitated electron transfer.

The architect complexes the design to test the engineers' problem-solving skills.

The engineer complexed the design to accommodate new features.

The complexed iron exhibited different spectral properties compared to the free ion.

The scientist observed the ligand complexing with the metal under the microscope.

The complexing of the metal ion with the ligand dramatically changed its spectroscopic properties.

The chemist's notes described several complexings that occurred during the titration.

The chemist studied several complexations that occurred when the ligand concentrations were varied.

The complexation of the metal ion with the ligand significantly altered its catalytic activity.

The laboratory stored the complexant under an inert atmosphere to prevent oxidation and preserve its ability to bind metal ions.
