[Mn(2,2′-bipy)₂S₆]_<i>n</i>: A Homochiral Hybrid of Manganese Polysulfido Compound with a One-Dimensional Mn-S₆-Mn Helical Chain

A novel manganese polysulfido hybrid, [Mn(2,2′-bipy)2S6]n, which is the first example with Qn2– (Q = S, Se, Te, n ≥ 1) as a bridging ligand connecting metal atoms to form a one-dimensional helical chain, has been synthesized and structurally characterized. The compound exhibits semiconducting properties (Eg = 1.67 eV) and strong blue photoluminescence with the emission maximum occurring around 400 nm, and the variable-temperature magnetic susceptibility data suggest a weak antiferromagnetic interaction among Mn2+ ions in the compound.
