3c-and 4c-Fe7Se8 contain large amount of ordered vacancies that define its magnetic structure. Combined comparative magnetic and Mossbauer investigation were performed to find out the peculiarities of the temperature magnetic transitions in these compounds. It was found that adding an additional layer with ordered vacancies in 4c superstructure increased the temperature of spin rotation.
