Abstract
The
one-dimensional complex [Mn<sup>III</sup><sub>2</sub>Cu<sup>II</sup>(μ<sub>3</sub>-O)(Cl-sao)<sub>3</sub>(EtOH)<sub>2</sub>]·EtOH
(Mn<sub>2</sub>Cu) was obtained by the metal replacement reaction
of the trinuclear manganese complex (Et<sub>3</sub>NH)[Mn<sup>III</sup><sub>3</sub>(μ<sub>3</sub>-O)Cl<sub>2</sub>(Cl-sao)<sub>3</sub>(MeOH)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>] with [Cu(acac)<sub>2</sub>]. The Mn<sub>2</sub>Cu chain exhibits single-chain-magnet
behavior with finite-size effects due to its large magnetic anisotropy
