摘要
The reaction of [(DippForm)(2)Ln(thf)(2)] with an excess of elemental sulfur in toluene resulted in the formation of the trinuclear polysulfide coordination clusters [(DippForm)(3)Ln(3)S(12)] (Ln = Sm, Yb; DippForm = N,N'-bis(2,6-diisopropylphenyl)formamidinate). These are the first felement coordination clusters (Ln(n)S(x)) with a larger polysulfide unit (n and x > 2). The formation of the coordination clusters can be rationalized by the reductive cleavage of S-8 with divalent lanthanides.
