Synthesis and structural characterization of new polynuclear complexes of 1-hydroxymethyl-3,5-dimethylpyrazole with Ni(II) and Fe(II)
摘要:
The complexation of the simple 1-hydroxymethyl-3,5-dimethylpyrazole (HL) ligand with Fe and Ni salts leads to interesting polynuclear complexes in good yield. X-ray diffraction reveals that the resulting complexes (mu(4)-L)(4)Ni4Cl4(H2O)(4) and (mu(2)-L)(4)(mu(3)-L)(2)Fe8Cl16(mu(4)-O)(6) adopt cubane-type and open-cubane-type structures in the solid state.
