Synthesis and molecular structure of piperazidine-bridged bis(phenolate) samarium(ii) complex and its reactivity to carbodiimides†
Abstract
The reaction of Sm[N(TMS)2]2(THF)2 with H2L (L = 1,4-bis(2-hydroxy-3-tert-butyl-5-methyl-benzyl)-piperazidine) afforded [SmL(HMPA)2]4·8THF 2 upon treatment with 2 equivalents of HMPA (
