experiment patterns and the simulated ones are in good
agreements, which confirms the purity of those complexes.
Therefore, the samples are pure enough for the study of their
properties.

slow evaporation. After 3 days, the clear dark brown block‐
shaped crystals of complex 1 were collected, washed with
ethanol and n‐hexane, and dried in a vacuum drying oven.
