- Аннотация: Depending on the synthetic conditions, five heterometallic (MnFeII)-Fe-III polynuclear compounds with the same ratio of constituents, 2[Mn(acacen)](+)/[Fe(CN)(5)NO](2-), of different nuclearity and dimensionality (0D, 1D, 2D) were isolated. A [Mn(acacen) MeOH](2)[Fe(CN)(5)NO]center dot 1.5MeOH, 1 complex has been prepared by reaction of Mn-III/Schiff base (SB) complex, [Mn(acacen)Cl] (H(2)acacen is N,N'-ethylenebis(acetylacetoneimine)) with sodium nitroprusside (NP). Single crystal X-ray diffraction analyses reveal that crystallization of 1 from coordinating or non-coordinating solvents results in different coordination polynuclear materials: from C2H5OH [{Mn(acacen)H2O}(2)Fe(CN)(5)NO]center dot C2H5OH, 2, a trinuclear complex is formed; from CH3CN [{Mn(acacen)H2O}(4)Fe(CN)(5)NO][Fe(CN)(5)NO]center dot 4CH(3)CN, an ionic compound with a pentanuclear bimetallic cation is formed 3; from i-C3H7OH [{Mn(acacen)}(2)(i-PrOH)Fe(CN)(5)NO](n), a coordination chain polymer 4 is formed; from toluene [{Mn(acacen)}(2)Fe(CN)(5)NO](n), a layered network 5 is formed. As the magnetic measurements show, for all compounds the weak interaction between Mn-III S = 2 spins through the NP bridge is antiferromagnetic and exhibits no significant photoactivity.
