Isolable zero-valent Ditin(0) and Diplumbum(0) complexes.

ABSTRACT: Although complexes with monatomic zero-valent main group centers have been reported, diatomic zero-valent complexes are extremely rare and all previously reported examples were stabilized by either carbene or silylene ligands. Here, we present the isolation of diatomic E(0)-E(0) (E = Sn, Pb) species supported by two [N{CH₂CH₂NPⁱPr₂}₃Sn] fragments. The reaction of trilithium salt N{CH₂CH₂NLiPⁱPr₂}₃ with SnCl₂ yields complex [N{CH₂CH₂NPⁱPr₂}₃]₂Sn₃ (1) with a Sn₃ chain. The reduction of the mixture of 1 and SnCl₂ with KC₈ produces the catenated Sn₄ chain [N{CH₂CH₂NPⁱ
