Abstract
The reaction of [(NdI)3N2] (I) with Cp3Er in the presence of sulfur in THF gave CpNdI2(THF), NdI(S2N2)(THF), and an unidentified erbium compound. A similar reaction of [(DyI)3N2] yielded CpDyI2(THF) and ErI(S2N2)(THF). When I reacted with ErCl3, the clusters [Nd2ErClI4-(S2)(S2N2)(THF)7] and [Nd2ErCl2I3(S2)(S2N2)(THF)7] were formed in 33–34% yield. From the mixture of reaction products of [(DyI)3N2] with sulfur and NdI3, only [Nd2DyI5(S2)(S2N2)(THF)7] was isolated in a minor yield and identified. Europium diiodide EuI2 almost did not react with complex I and sulfur under the chosen conditions. The starting EuI2 (50%) and previously characterized cluster [Nd3I5(S2)(S2N2)(THF)9] were isolated from the reaction mixture.
