Article Synopsis

Two one-dimensional coordination polymers (I and II) were synthesized, consisting of high-spin and low-spin Mn complexes connected by cyano groups.
Compound I exhibits single-chain magnet behavior, showing stabilization from magnetic interactions with an energy barrier of approximately 40 K.
The magnetic properties of I are unique due to unconventional spin coupling between the manganese complexes, presenting a potential for developing new molecular magnets.
