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 â‰Š 10-12 K) is observed.
