Synthesis and crystal structure of the silver(I) alkyl species, [{2-(Me3Si)2C(Ag)C5H4N}2], a dimeric compound void of electron-deficient bonding

Abstract

The silver (I) alkyl complex [{2-(Me₃Si)₂C(Ag)C₅H₄N}₂], prepared by the reaction of the analogous lithium alkyl with AgBF₄ in tetrahydrofuran, is a binuclear complex in which the metal ion is not involved in electron-deficient bonding, being bound by a carbon atom at 2.154(5)Å and a nitrogen atom of a centrosymmetrically related ligand at 2.160(5)Å; the Ag ⋯ Ag′ separation is 2.654 (1)Å.
