ИСТИНА

Polynuclear coordination compounds containing high-spin atoms of transition elements are the objects of attention of specialists in different fields. The interest is caused by the possibility of their application as molecular magnets. These substances are magnetized when placed in an external magnetic field and retain their magnetization after the field is turned off. Heteropolynuclear clusters are considered to be the most promising. Due to the use in coordination polymers of various metal ions containing unequal values of the total spin, it is possible to obtain a ferromagnetic system, which is characterized by all the necessary magnetic properties. During the research work holmium-manganese complexes with para-tert-butylthiacalix[4]arene were synthesized under standard (room) conditions and under the action of microwaves
