I identified the unknown sample on the basis of preliminary measurments and the basic data of its synthesis and physical properties. To identify the sample, I used the results of the analyses of different characterization techniques, such as data on sample purity and solubility, CHN elemental analysis, infrared spectroscopy, electron spectroscopy, conductivity measurements. On the basis of the results of the analyses I concluded that the unknow sample is (pyH)[MoCl4py2]. From the data retrieved from the CCDC I established that two polymorphic forms of the compound are known. With Mercury program I studied their crystal structures and obtained the calculated diffractograms.
