Two novel compounds [Mn(salen)(dmf)2]3[Mn(salen)(dmf)(H2O)][CdCl4]2·H2O(1) and {[Mn(salen)(CH3OH)]2}[Mn(salen)(CH3OH)2]2[CdI4]2(2) have been synthesisedviainteraction of manganese metal and cadmium halidewithin situgenerated salen ligand (salen=N,N′-ethylene-bis-salicylideneaminato) in non-aqueous (dmf, CH3OH)solutions. X-ray structure analysis reveals that in solid state1contains mononuclear MnIII–salen species, whilst in2both monomeric and out-of-plane dimeric MnIII–salen complexes are present. Moreover, in2the monomeric unitsare linked by H-bonds, forming other dimers. Equilibrium between monomeric and dimeric units in solutions of1and2was found by ESI mass-spectrometry. The magnetic measurements of2demonstrated antiferromagneticinteractions between MnIIIcentres.
