abstract in English:	Substitution of the organic cation X in the 1D polymer, (X)_{2}[Mn(acacen)Fe(CN)_{6}], leads to an essential change in magnetic behavior. Due to the presence of more voluminous Ph_{4}P^{+} cations, the polyanion has a more geometrically distorted chain skeleton and, as a consequence, enhanced single chain magnet (SCM) characteristics compared to those for Et_{4}N^{+}. The Arrhenius relaxation energy barriers, the exchange interaction constant and the zero-field splitting anisotropy of Mn^{III} are determined from the analysis of magnetic measurements. The discussion is supported with ligand field calculations for [Fe(CN)_{3}]^{3-} that unveils the significant anisotropy of Fe magnetic moments.
