摘要

A series of mononuclear and dinuclear zinc compounds, [Na(Et 2O)]2[(HLiPr)Zn-Zn( HLiPr)]·Et2O (1), [Zn2( HLiPr)3K2(Et2O) 2]n (2, HLiPr = [(2,6- iPr2C6H3)NCH]2), [Zn(HLMes)2] (4, HLMes = [(2,4,6-Me3C6H2)NCH]2), and [ZnLMes2Na2(THF)2] (5, L Mes = [(2,4,6-Me3C6H2)NC(Me)] 2), and a potassium complex, [(HLiPr) 2K4(THF)2]n (3), have been synthesized by alkali metal reduction of the corresponding LZnCl2 precursors. The Zn-Zn bond in 1 (2.3673(6) Å) is slightly shorter than that in the analogous compounds [M(THF)2]2[L iPrZn-ZnLiPr] (LiPr = [(2,6-iPr 2C6H3)NC(Me)]2, M = Na, 2.399(1) Å; M = K, 2.393(1) Å). Complexes 2 and 3 feature a two- and one-dimensional (linear chain) polymeric structure, respectively, linked by K-C bonds between the potassium ion and aryl carbon atoms. Notably, complex 2 contains a ligand whose central C2N2 core is in the trans conformation, acting as a non-chelating bridge between the two zinc atoms. While the ligands in 1, 2, 3 and 5 are doubly reduced to the dianion, complex 4 contains a pair of monoanionic ligands.
