摘要：
Two novel complexes, namely [Cu2(L)2] (1) and [Ni4(L)4] (2, H2L = 1-{3-[(5-bromo-2-hydroxy-benzylidene)-amino]-2-hydroxyphenyl}-ethanone) were synthesized through solvothermal methods at the same condition. The complexes 1 and 2 were characterized by IR spectroscopy, elemental analysis and single-crystal X-ray diffraction. 1 is dinuclear copper complex while 2 is a cubane nickel cluster. The L ligand displays two different coordination modes. One is the μ1-L-κ3N1:O1:N2 coordination mode and the other is μ3-L-κ6O1:O2:O2:O2:N1:O3 coordination mode. Magnetic studies reveal that the complex 2 displays dominant antiferromagnetic intracluster interactions between the NiII ions through the μ3 oxide bridges with g = 2.29, J =  − 0.939 cm−1, and zJ′ =  − 0.333 cm−1. Hirshfeld surface analysis revealed that H···H interaction was the dominant intermolecular interaction.
