dc.description.abstractEn | Using di-2-pyridyl ketonoxime (Hdpko) as an oxime-based ligand in combination with several polyhydric alcohols, viz. ethanediol (H2ed), propanediol (H2pd) and pentaerythritol (H4per),wehave synthesized a series of trinuclear complexes involving a linear MnII-MnIV-MnII core, viz. [Mn3(dpko)4(ed)Cl2]-2CH3CN.H2O 1, [Mn3(dpko)4(pd)Cl2].CH3CN.H2O.0.5H2pd 2 and [Mn3(dpko)4(H2per)Cl2].4H2O 3, respectively. The trinuclear complexes contain mixed valent MnII-MnIV-MnII units in a linear topology in which MnII and MnIV spin carriers are ferromagnetically coupled. The temperature dependence of the magnetic susceptibility has been fitted with a liner spin trimer model based on the H = -2J{SMn1.SMn2 + SMn10.SMn2} Heisenberg Hamiltonian with J/kB = +1.4(1) K for 1; +4.9(1) K for 2 and +3.7(1) K for 3, leading for the three complexes to an ST = 13/2 ground state. | |
