By analysing the results of the selected methods, I confirmed the composition of two samples of similar chemical composition, in which chloride or bromide ligand were present. I did the deconstruction of the samples and then determined the halide content in the residues formed after the decomposition, based on gravimetric analysis and potentiometric titration. To characterize the samples of compounds (NH4)2[MoX5H2O] (X = Cl (1), Br (2)), I also used the results of elemental CHN analysis, vibrational and electronic spectroscopy, X-ray powder analysis and magnetic measurements.
