The four ionic manganese(III) and iron(III) dipicolinate complexes of formula (Hpia)[FeIII(dipic)2]·3H2O, (Hpia)[MnIII(dipic)2]·(H2dipic)·6H2O, (Hinia)[FeIII(dipic)2]·3H2O and (Hinia)[MnIII(dipic)2]·3H2O, where dipic2−=pyridine-2,6-dicarboxylate anion (dipicolinate anion), H2dipic=pyridine-2,6-dicarboxylic acid, Hpia+=2-carboxamidepyridinium (picolinamidium) cation and Hinia+=4-carboxamidepyridinium (isonicotinamidium) cation have been prepared and characterized by the single-crystal X-ray structure analysis. The SQUID-magnetic data were fitted to a zero-field splitting model revealing a slight magnetic anisotropy: |D|/hc∼3cm−1 for Mn(III).
