“…Although As and Se are indistinguishable in XRD, the inner ligands in the {Re 4 (AsO) 3 Se} 5+ cluster core occupy strictly defined positions: each of the three arsenic atoms is bonded to an oxygen atom, the position of which is fully occupied. The As–O distances have typical values of 1.641(12)–1.676(9) Å. , As in the case of the sulfide complex described above, the geometry of the cluster core is distorted, but to a much lesser extent. Thus, the Re–Re distances for the face coordinated by the selenide ligand vary from 2.8588(7) to 2.8625(7) Å and are slightly shorter than the other bonds in the tetrahedron, which are 2.9143(7)–2.9332(7) Å.…”

Reactivity of new tetrahedral rhenium cluster complexes with pnictogenide inner ligands μ3-As3–, μ3-Sb3–, and μ3-Bi3– has been investigated in reactions with aqueous H2O2. It has been found that the oxidation of clusters [{Re4As3Q}(CN)12]7– (Q = S or Se) led to the formation of stable clusters with μ3-(AsO)3– ligands. Under the same conditions, the oxidation of [{Re4As2S2}(CN)12]6– cluster led to substitution of μ3-As3– ligands to μ3-O2–. The resulting cluster [{Re4O2S2}(CN)12]4– easily undergoes further oxidation, and even at room temperature, a unique {Re4} to {Re3} rearrangement occurs with the formation of the new triangular cluster [{Re3(μ3-S)(μ-O)2(μ-SO2)}(CN)9]5–. Upon heating, this process proceeds faster and the triangular cluster can be isolated as individual compounds. Cluster anions [{Re4SbSe3}(CN)12]5– and [{Re4BiS3}(CN)12]5– reacted with H2O2, yielding clusters containing μ3-O2– ligands, namely, [{Re4OSe3}(CN)12]4– and [{Re4OS3}(CN)12]4–. This indicates that oxidized forms of μ3-Sb3– and μ3-Bi3– ligands can be easily substituted.
