摘要

Reaction of Mn(OAc)_2·4H_2O with the H_2L ligand affords a new manganese 22-MC-8 azametallacrown [Mn_8(μ_3-O)_2(μ_3-OH)_2(μ_2- OH)_2(L)_6(OAc)_2(OH_2)_4]·2DMF (H_2L = 3-(2-oxyphenyl)-5-(pyrazin-2- yl)-1,2,4-triazole). The structural analysis of the complex reveals that the azaMC ring possesses -[Mn-O-Mn-N-N-Mn-N-N- Mn-N-N]- connectivity. The magnetic behavior of the complex shows the dominant antiferromagnetic interactions between the manganese ions with S = 4 and the frequency-dependent out-ofphase signal.
