Abstract

The reaction of 2-hydroxyphenylpropanone oxime (Et-H2salox) with Mn(NO3)2·4H2O, NEt3 and 1,3-bis(4-pyridyl)propane-N,N′-dioxide (bppo) in EtOH/H2O mixture afforded a one-dimensional coordination polymer with the formula [Mn3O(Et-salox)3(bppo)(MeOH)(H2O)3](NO3)0.5(Et-Hsalox)0.5·MeOH·H2O (1·MeOH·H2O). 1·MeOH·H2O had a manganese triangle structure, [MnIII3O]7 +, which was used as a building unit for a subsequent assembly of an oximate and central oxide. The flexible bppo ligand linked the units, resulting in the formation of a 1D helical structure. Variable temperature direct current magnetic susceptibility measurements of complex 1·MeOH·H2O were carried out. Exchange interactions of the metal centers of complex 1·MeOH·H2O were examined, and the results indicate that both ferro- and antiferromagnetic interactions simultaneously coexist in 1·MeOH·H2O, resulting in an S = 2 ground state. Moreover, complex 1·MeOH·H2O shows the frequency dependence of the out-of-phase component in alternating current magnetic susceptibility measurements, indicating single-molecule magnet behavior with Ueff = 28 K and τ0 = 1.8 × 10- 9 s.
