EnglishTwo pentanuclear NiII complexes, [Ni5(L1)2(CH3COO)6(OH)2- (MeOH)2] (1) and [Ni5(L2)2(CH3COO)6(OH)2(H2O)2] (2), and one tetranuclear CuII complex, [Cu4(L3)2(CH3COO)4(O)] (3), have been synthesized from phenol-based “end-off” compartmental ligands HL1 to HL3 {HL1 = 2,6-bis[ethyl(2- thienyl)iminomethyl]-4-tert-butylphenol; HL2 = 2,6-bis- [ethyl(2-thienyl)iminomethyl]-4-chlorophenol and HL3 = 2,6- bis[ethyl(2-thienyl)iminomethyl]-4-methylphenol, respectively}. The complexes have been structurally characterized and their magnetic properties have been investigated within the temperature range 2.2–300 K. Complexes 1 and 2 comprise two dinuclear [Ni2L2] units linked to a central Ni ion by bridging μ3-hydroxo groups.
