Abstract
New complexes of Co(II), Ni(II), and Cu(II) chlorides with 3-amino-4-ethoxycarbonylpyrazole (L) of the composition ML2Cl 2 are synthesized. The compounds are studied by powder X-ray diffraction, electronic and IR spectroscopy, static magnetic susceptibility (temperature range 2-300 K). It is found that in the ML2Cl 2 complexes (M = Co(II), Ni(II), Cu(II)) ferromagnetic exchange interactions between the unpaired electrons of metal ions occur. In [CoL 2Cl2] and [NiL2Cl2] compounds a transition to the magnetically ordered state (T c ≊ 10-12 K) is observed.
