A new molecular magnetic compound, formulated as {[Mn2(L)2(C6H4ClSeO2)]2(ClO4)2}n (1) [H2L = 2,2′-((1E,1′E)-(ethane-1,2-diylbis(azaneylylidene))bis(methaneylylidene))diphenol], has been synthesized, and analysed in terms of its structure and magnetic properties. The complex features a one-dimensional polymeric chain in which the Mn(III) ions are connected via a double phenoxido bridge and O–Se–O bridge. The magnetic behavior of the 1-D compound revealed canted antiferromagnetic interactions and SCM behavior characterized by Δτ = 36.9 K with pre-exponential factor τ0 = 3.99 × 10−9 s. It was noted that this SCM behavior was accompanied by a magnetic order leading to a canted antiferromagnet. This compound stands as an uncommon instance of an O–Se–O bridged Mn(III) system displaying SCM characteristics.
