Abstract / Description of output

Three novel cationic hexametallic Mn(III) compounds of formulae [Mn-6(mu(3)-O)(2)(H2N-sao)(6)(py)(6)(EtOH)(2)]-(ClO4)(2)center dot 4EtOH (1), [Mn-6(mu(3)-O)(2)(H2N-sao)(6)(tpy)(6)(H2O)(2)](ClO4)(2)center dot 2tpy center dot 4H(2)O center dot 2EtOH (2) and [Mn-6(mu(3)-O)(2)(H2N-sao)(6)(Him)(6)(EtOH)(2)](ClO4)(2)center dot 6EtOH (3) [H2N-saoH(2) = salicylamidoxime, py = pyridine, tpy = 4-tert-butylpyridine and Him = imidazole] have been synthesised and magnetostructurally characterised. These [Mn-6](2+) complexes are new members of the oxime-based family of neutral [Mn6] single-molecule magnets (SMMs) in which the previously terminally bonded carboxylates, phosphinates, halides or ROH molecules on the outwardly facing triangular faces have been replaced with pyridine (1), 4-tert-butylpyridine (2) and imidazole (3) molecules generating a new series of salts based on Mn-6 complexes. These results suggest that the cationic [Mn-6](2+) species could be used as suitable building blocks for preparing new materials with different functionalities.
