Аннотация:The cationic complexes of Mn(III) with the 5-Hal-sal2323 (Hal = Cl, Br) ligands and a paramagneticdoubly charged counterion [ReCl6]2- have been synthesized: [Mn(5-Cl-sal2323)]2[ReCl6](1) and [Mn(5-Br-sal2323)]2[ReCl6] (2). Their crystal structures and magnetic properties have beenstudied. These isostructural two-component ionic compounds show a thermally induced spin transitionat high temperature associated with the cationic subsystem and a field-induced slow magneticrelaxation of magnetization at cryogenic temperature, associated with the anionic subsystem. Thecompounds are the first examples of the coexistence of spin crossover and field-induced slow magneticrelaxation in the family of known [MnIII(sal2323)] cationic complexes with various counterions.
