Abstract:
Wheel-type heptanuclear heterometallic clusters of stoichiometry [Ni7-xMx(HL)6(μ3-OMe)4(μ3-OH)2]Cl2 (L = 1-(2-hydroxy-3-methoxybenzamido)-2-(benzylideneamino)ethane; M = Zn2+, Co2+, Mn2+; x = 1, 3) were synthesized, and their metal ion dependent ferromagnetic properties were investigated. It was demonstrated that the central position of each cluster was occupied by a Ni2+ ion while other metal ions (Zn2+, Co2+ or Mn2+) were accommodated in peripheral positions. The magnetic interactions, anisotropy and magnetization of the resultant clusters were all influenced by the combinations of metal ions present.
