Abstract

Heating MnBr(CO)₅ with Ph₂Te₂ in boiling benzene yields diamagnetic Mn₂(CO)₈(μ-TePh)₂ (I), while the photochemical reaction of Mn₂(CO)₁₀ with Ph₂Te₂ in boiling tetrahydrofuran yields paramagnetic Mn₂(CO)₆(μ-TePh)₃ (II) containing one unpaired electron (μ_eff = 2.5 μ_B at 296-78 K). According to X-ray structural analysis, I and II contain two and three PhTe bridges respectively. The Mn-Te bonds in II [2.622(1)-2.654(1) Å] are slightly shortened compared to those in I [2.655(6)-2.684(7) Å]. No Mn-Mn bonding occurs in I [Mn⋯Mn distances are 3.921(6) and 4.019(6) Å in the two independent molecules; MnTeMn angles are 95.2(2) and 97.2(2)° respectively], while one-electron metal-metal bonding is observed in II [Mn-Mn 3.058(1) Å MnTeMn angle 70.5(1)-71.2(1)°].
