Abstract

Two ferromagnetic multinuclear Ni(ii) clusters, [Ni 4 L 1 43 -OMe) 4 (CH 3 OH) 4 ] (1) and [Ni 7 (HL 2 ) 63 -OMe) 6 ]Cl 2 (2), and a mononuclear complex [NiL 3 ]·2H 2 O (3) (HL 1 = benzyl 2-hydroxy-3-methoxybenzoate; H 2 L 2 = 1-(2-hydroxy-3-methoxybenzamido)-2-(benzylideneamino)ethane; H 2 L 3 = 1-(2-hydroxy-3-methoxybenzamido)-2-(pyridylmethyleneamino)ethane) were synthesised, and their structures and magnetic behaviours were investigated in detail. 1 has a [Ni 4 O 4 ] cubane structure while 2 has a wheel-like [Ni@Ni 6 ] arrangement. The temperature-dependent magnetic susceptibilities for 1 and 2 are in accord with the presence of dominating intra-cluster ferromagnetic interactions between Ni(ii) ions. The best fits for their behaviours gave the following parameters: J 1 = 11.06 cm -1 , J 2 = 1.43 cm -1 , g = 2.29 for 1, and J 1 = 6.87 cm -1 , J 2 = -3.41 cm -1 , g = 2.24 for 2.
