Purpose: to create and study the properties of new heterocyanometal complexes and materials based on them with a wide range of characteristics of the spin transition, to find the relationship between the composition, structure and functional properties of the studied compounds. Research methods: X-ray diffraction of single crystals and powders, magnetometry, optical microscopy, Mössbauer and IR spectroscopy, calorimetry. New ferrous-containing cyanoheterometal complexes with spin transition based on 1,6-naphthyridine composition [Fe-1,6-naphthy) 2 (Ag (CN (2) 2]), based on pyridazine of general formula [Fe (pdz) 2M (CN) 4] (where M = Ni, Pd, Pt), based on methylpyrazine composition [Fe (Mepz) (Au (CN) 2) 2] and [Fe (Mepz) 2] (Ag (CN) 2) 2], based on phthalazine of General formula [Fe (phth) 2M (CN) 4] (where M = Pd, Pt), based on 2-phenylpyrazine (Phpz) of General formula [Fe (Phpz) 2 {M (CN) 2} 2] (where M = Ag, Au). Crystal structures of all complexes obtained by X - ray diffraction were established. Conducting magnetic, optical and calorimetric studies have confirmed the presence of a spin transition and allowed to determine the transition temperature and thermal effects. It was obtained and studied composite films with a spin transition, which is characterized by bistability. Product Description popup.authors Bibik Yuri М. Giyuk Volodymyr M. Naumova Dina D.
