摘要：

A new trinuclear manganese cluster, [Mn-3(O2CCH3)(4)(sae)(2)(HIm)(2)] (1) (H(2)sae = 2-salicylideneaminoethanol, HIm = imidazole), has been prepared. Single crystal X-ray diffraction analysis reveals an interesting one-dimensional supramolecular arrangement of the [Mn-3(O2CCH3)(4)(sae)(2)(HIm)(2)] trimers induced by HIm axial ligands and hydrogen bonding interactions. The magnetic measurements show that trimer units in 1 exhibit an S-T = 3/2 ground state and order antiferromagnetically below 0.37 K. (C) 2004 Elsevier B.V. All rights reserved.
