摘 要: | By use of a new ligand containing both salicylic acid moiety and salicylaldehyde Schiff base moiety, 5-(2-hydroxybenzylideneamino)-2-hydroxybenzoic acid (H3L), a linear trinuclear Mn(II) complex was prepared. This complex crystallizes in triclinic, space group P1 with a = 12.0196(7), b = 13.7440(13), c = 15.7554(14) , α = 111.529(3), β = 96.691(2), γ = 94.802(2)o, C96H100Mn3N6O32, Mr = 2014.64, V = 2382.0(3) 3, Z = 1, μ = 0.478, Dc = 1.404 g/cm3, F(000) = 1049, R = 0.0554 and wR = 0.1610 for 8973 observed reflections (I 2σ(I)). The complex consists of a trinuclear cluster and two solvate ethanol molecules. Three linearly disposed Mn atoms, with an inversion center on the central one, are bridged by six carboxylate groups from six bulky mono-anionic ligands (H2L–), and the octahedral coordination spheres for each of the metal centers are thus formed, with the aid of additional ligation of two small molecules (ethanol and water) to both ends. The magnetic properties of the title complex are also included in this paper.
