Abstract: 

We report on the results of the X-ray diffraction study of (N(CH3)4)2MnCl4 crystals. The structure data are obtained by the Rietveld method. The (N(CH3)4)2MnCl4 compound is crystallized in a monoclinic lattice with the space group of P21/c (14). The results of the infrared spectroscopy of (N(CH3)4)2MnCl4 crystals are presented at 270 K. Photoluminescence emission spectra are studied for (N(CH3)4)2MnCl4. A broad band located approximately at 520 nm and its nature is discussed. Photoluminescence excitation spectra are measured for the band located at 520 nm and their parameters are evaluated.

Keywords: 
crystal structure, infrared spectroscopy, vibration spectra, photoluminescence, emission spectra.
