Two cubane-like [M4O4] {M = nickel(II), cobalt(II)} complexes: syntheses, crystal structures and magnetic properties

  • 26 Accesses


Two cubane-like complexes, namely [Ni4L4(HOEt)4] (1), [Co4L4(HOEt)4] (2) (H2L = (E)-2-((3-hydroxypropylimino)methyl)-6-methoxyphenol), were prepared under solvothermal conditions. Structural analyses show that complexes 12 are tetranuclear complexes with a cubane topology in which four M atoms and four µ3-O atoms occupy the alternate vertices of the cubane. The magnetic properties of them have been investigated. Antiferromagnetic interactions were observed for complexes 1 and 2.
