N2 - By the reaction of M(hfac) 2 (M = Mn(II), Co(II), Cu(II), and Zn(II); hfac is the hexafluoroacetylacetonate anion) and ferrocenyl-substituted nitronyl nitroxide (L), we succeeded in the synthesis of stable heterospin complexes: mononuclear [Zn(hfac) 2L], trinuclear {[Cu(hfac) 2] 3L 2} and chain polymer [Mn(hfac) 2L] n and [Co(hfac) 2L] n . The specific steric bulkiness of the ferrocenyl substituent leads to the formation of trans-type coordination polyhedra in the [Mn(hfac) 2L] n and [Co(hfac) 2L] n chains. The introduction of the ferrocene substituent leads to an effective weakening of intermolecular or interchain magnetic exchange coupling. Ferrimagnetic ordering was observed for one-dimensional complexes [M(hfac) 2L] n (M = Mn(II), Co(II)). [Co(hfac) 2L] n exhibits features of single-chain magnet behaviour: slow relaxation of magnetization below 13 K is associated with a high coercive field (54 kOe at 2 K).
