Abstract: At present, studies are carried out in the field of coordinate compounds of rare-earth elements (REEs), particularly, different-ligand complexes. Different-ligand complexes, containing rare earth elements and organic substances, attract the attention of scientists. This is due to a wide range of physical, chemical and product properties of such materials, as well as the increasing demands of the high technology modern market in new materials. Further to the study of the properties of coordinate compounds with REEs, a new coordinate compound of [La(HMPA)4(NO3)2][Cr(NH3)2(NCS)4] has been synthesized, where HMPA = ((CH3)2N)3PO (I) .

Key words: lanthanum(III) tetra(isotiocyanato)diaminechromates(III)-ion hexamethylphosphorutriamide IR-spectroscopy differential scanning calorimetry (DSC)
