摘要：
Two novel compounds [Mn(salen)(dmf)(2)](3)[Mn(salen)(dmf)(H2O)][CdCl4](2)center dot H2O (1) and ([Mn(salen)(CH3OH)](2)) [Mn(salen)(CH3OH)(2)](2)[Cdl(4)](2) (2) have been synthesised via interaction of manganese metal and cadmium halide with in situ generated salen ligand (salen = N,N'-ethylene-bis-salicylideneaminato) in non-aqueous (dmf, CH3OH) solutions. X-ray structure analysis reveals that in solid state 1 contains mononuclear M-III-salen species, whilst in 2 both monomeric and out-of-plane dimeric M-III-salen complexes are present. Moreover, in 2 the monomeric units are linked by H-bonds, forming other dimers. Equilibrium between monomeric and dimeric units in solutions of 1 and 2 was found by ESI mass-spectrometry. The magnetic measurements of 2 demonstrated antiferromagnetic interactions between Mn-III centres. (C) 2012 Elsevier B.V. All rights reserved.
