Abstract
New adducts with the composition [Co2Gd(NO3)(Piv)6L2] (L=2,4‐lutidine (lut) (1), 2‐phenylpyridine (PhPy) (4), 2‐ethynylpyridine (EtPy) (5)) and [Co2Eu(NO3)(Piv)6(EtPy)2] (6) were synthesized. According to X‐ray diffraction data, the molecular complexes comprise two atoms of cobalt(II) and one central atom of gadolinium(III) bridged by carboxylate ligands. The donor base molecules are coordinated to cobalt atoms. Magnetic measurements of the new and previously synthesized complexes with quinoline (2) and pyridine (3) ligands showed the ferromagnetic nature of the coupling between the metal centers in the CoII2GdIII core with JCo‐Gd parameters in the range of 0.15−0.18 cm−1. DFT calculations supported the ferromagnetic type of coupling for these complexes. Simultaneous thermal analysis of 1 and 2 showed the thermal stability of the complexes up to 180 °C and the stepwise nature of thermolysis, which includes the stages of elimination of the donor base molecules and the thermal decomposition of the pivalate moieties in the complex.
