Characterization and Crystal Structure of a Novel Mononuclear Cobalt(II) Complex with Hydrazone Derived from Protocatechuic Acid

Аннотация

A novel complex [Co^II(L)₂·CH₃OH] with hydrazone derived from protocatechuic acid (HL=C₁₆H₁₄N₂O₄) is designed and synthesized. The complex is characterized by single crystal X-ray diffraction, elemental analysis, IR, and thermal gravimetric analysis. The complex crystallizes in the monoclinic space group C2/c, with unit cell dimensions a = 25.1715(11), b = 9.3518(4), c = 12.8700(6) Å, β = 103.6530(10)°, V = 2943.98(75) ų, Z = 4, R₁ = 0.0612, and wR₂ = 0.1439.
