  Subtle anion effects on molecular construction: “Metallocyclic dimer” vs “molecular strands”

  摘要：

  Studies on the subtle anion effects on the self-assembly of a series of AgX with a new organic spacer, L (X- = CF3SO3-, CIO4-, BF4(-); L = 1,2-bis(dimethyl-3-pyridyisilyl)ethane) were carried out. The slow diffusion of an organic solution of L into an aqueous solution of AgX affords the composition of [Ag(L)]X. The conformation of L is non-rigid, and thus the molecular construction is delicately dependent on the nature of the anions. For the CF3SO3 anion, L connects two Ag(I) ions (Ag(1)-N = 2.150(6), 2.153(6) angstrom; Ag(2)N = 2.133(6), 2.144(6) angstrom) to form a 22-membered metallocyclic dimer [Ag2L2](CF3SO3)(2). The CF3SO3- anion is placed between two distinct units, resulting in an infinite quasi-one-dimensional chain arrays via weak Ag center dot center dot center dot O interactions (Ag center dot center dot center dot O = 2.683, 2.721, 2.904, and 2.948 angstrom). By contrast, for the CIO4- and BF4- anions, L connects two silver(l) ions in a bridged fashion to give a single strand. Moreover, the single strands are extended in two directions with respect to each other by a 37.7 degrees rotation and stacked alternately on the [100] direction. Such subtle effects may be ascribed to the metallophilic nature of counteranions. Thermal analyses indicate that both the metallocyclic dimer and the single strand are stable up to 250 degrees C in the solid state. (C) 2007 Elsevier B.V. All rights reserved.
