Influence of the Coligand onto the Magnetic Anisotropy
and the Magnetic Behavior of One-Dimensional Coordination Polymers
Posted on 2020-06-18 - 16:11
Reaction of Co(NCS)2 with different coligands leads
to the formation of three compounds with the general composition [Co(NCS)2(L)2]n (L = aniline
(1), morpholine (2), and ethylenethiourea
(3)). In all of these compounds the cobalt(II) cations
are octahedrally coordinated by two trans thiocyanate
N and S atoms and the apical donor atoms of the coligands and are
linked into linear chains by pairs of anionic ligands. The magnetic
behavior was investigated by a combination of static and dynamic susceptibility
as well as specific-heat measurements, computational studies, and
THz-EPR spectroscopy. All compounds show antiferromagnetic ordering
as observed for similar compounds with pyridine derivatives as coligands.
In contrast to the latter, for 1–3 significantly higher critical temperatures and no magnetic single-chain
relaxations are observed, which can be traced back to stronger interchain
interactions and a drastic change in the magnetic anisotropy of the
metal centers. These results are discussed and compared with those
of the pyridine-based compounds, which provides important insights
into the parameters that govern the magnetic behavior of such one-dimensional
coordination polymers.
