    Abstract: The syntheses, structures, and magnetic properties of two new μ-alkoxo-μ-pyrazolato heterobridged compounds, [Cu II2(L1-F)(μ-prz)] (1) and [Cu II2(L1-2OMe) (μ-prz)] · 0.5 CH3CN (2) (prz=pyrazolato; H2L1-F=1,3-bis(3-fluorosalicylideneamino)-2-propanol; H2L1-2OMe=1,3-bis(4,6-dimethoxy salicylideneamino)-2-propanol) have been reported. Compound 1 crystallizes in triclinic
    space group with a=8.6392(10) Å, b=10.6431(9) Å, c=11.6809(13) Å, α=85.972(8)°, β=71.492(9)°, and γ=72.221(9)°, while the unit cell parameters of 2 are as follows: space group: monoclinic C2/c, a=28.2948(5) Å, b=7.3033(2) Å, c=26.3933(5) Å, and β=96.243(1)°. The variable-temperature magnetic susceptibility measurements reveal that the metal centers in both the compounds are antiferromagnetically coupled with J=−200 cm−1 for 1 and J=−175 cm−1 for 2. The magnetic behaviors have been explained on the basis of two opposing factors, complementarity and countercomplementarity of magnetic orbitals.

    The syntheses, structures, and magnetic properties of two new heterobridged μ-alkoxo-μ-pyrazolato compounds derived from substituted 1,3-bis(salicylideneamino)-2-propanol) ligands have been described. Both the two complexes exhibit moderate intramolecular antiferromagnetic interaction (J=−200 cm−1 for one complex and J=−175 cm−1 for other
    . The magnetic behaviors, have been explained on the basis of two opposing factors, complementarity and countercomplementarity of magnetic orbitals.
