Abstract

A series of eight adducts of the form (RR'R"N)(2)center dot Zn(C6F5)(2) have been prepared through treatment of the Lewis acid Zn(C6F5)(2) with 2 equiv of the corresponding amine (R = Bu-t or CH2Ph, R' = R" = H; R = R' = Me or CH2Ph, R" = H; R = Me, R' = CH2Ph, R" = H; RR' = cyclo-C4H8 or cyclo-C5H10, R" = H; R = R' = Me, R" = CH2Ph). The solid-state structures of all eight compounds have been elucidated by single-crystal X-ray diffraction. In each case the geometry about the zinc atom is essentially tetrahedral. However, there is considerable variation in the supramolecular architectures in the solid state. A number of types of noncovalent interactions are observed including phenyl-pentafluorophenyl stacking, X-H center dot center dot center dot F-C contacts, and offset face-to-face contacts between pentafluorophenyl rings, giving rise to one-, two-, and three- dimensional supramolecular structures. In our examples we find that no one intermolecular interaction predominates.
