Abstract

Two complexes with Co2+and 3-hydroxypicolinic acid, [Co(picOH)2(H2O)2] (I) and mer-[N(CH3)4][Co(picOH)3]·H2O (II), have been synthesised and characterised using single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy, and thermoanalytical measurements. The 3-hydroxypicolinate ligands are coordinated to the Co2+centres via its typical N,O-chelating coordination fashion. While in I the presence of two coordinated water molecules leads to the formation of a neutral [Co(picOH)2(H2O)2] complex which is strongly hydrogen bonded to another four neighbouring complexes, in II the inclusion of a third picOH-ligand leads to an anionic octahedral complex, [Co(picOH)3]-, in which all the N- and O-atoms are occupying mer positions. The properties of these two compounds were further investigated by measuring their magnetic behaviour. © 2005 Elsevier Ltd. All rights reserved.
