On the Reactivity and Stability of Iodide-Nitride-Sulfide Clusters of Neodymium and Dysprosium

摘要

The thermal decomposition of cluster Nd3I5(S-2)(S2N2)(THF)10 (I) at 50-400A degrees C affords a mixture of products among which tetrahydrofuran (THF), sulfur, diiodine, HI, H2S, CS2, S3N6, S3N5, MeI, thiophene, tetrahydrothiophene, diiodobutane, iodobutene, and NdI3 are identified. The treatment of Ln(3)I(5)(S-2)(S2N2)(THF)(10) (Ln = Nd (I), Dy (II)) with phenanthroline (Phen) in THF at room temperature results in the partial substitution of D cent DeF to form new complexes Ln(3)I(5)(S-2)(S2N2)(THF)(4)(Phen)(3). The dissolution of compound I in pyridine gives a pyridine (Py) complex Ln(3)I(5)(S-2)(S2N2)(THF)3(Py)(7). The dissolution of compounds I and II in acetonitrile at 20A degrees C is accompanied by the fast rearrangement and fragmentation of the complexes to form LnI(3)(MeCN)(6), [LnI(S-2)(MeCN)], and [LnI(S2N2)(MeCN)]. Complex I in THF does not react with white phosphorus, carbon monoxide, fullerene C-60, and chromium hexacarbonyl.
