Abstract

Single crystal X-ray structural characterizations of some adducts of silver(I) nitrate and perchlorate with assorted organic poly-ene ligands (nbd = norbornadiene, bicyclo[2.2.1]hepta-2,5-diene; cod = 1,5-cyclooctadiene; cdt equivalent to trans,trans,cis-cylododeca-1,5,9-triene) 9 are reported, all being polymeric in form (with the exception of mononuclear ionic AgClO4:cod (1:2)), with chains comprised of alternating silver and nitrate/perchlorate components substituted or linked by unsaturated donors which complete the coordination spheres of the silver atoms. In AgNO3:nbd (2:1) (a redetermination), pairs of silver/nitrate strands are linked in a one-dimensional polymer by the nbd ligands. In AgNO3:nbd (1:1)(infinity), meandering silver/nitrate strands containing pairs of independent silver and nitrate units in a crystallo-graphic mirror plane are linked to either side with parallel planes by nbd ligands. In AgNO3:cod (1:1)(infinity), the cod ligands 'chelate' to the silver atoms in a silver/nitrate chain. In AgNO3:cdt (1:2)(infinity), pairs of 'unidentate' cdt ligands are pendant from a silver/nitrate chain, while in the (1: 1)(infinity) adduct, the cdt ligands bridge pairs of silver atoms from an adjacent chain forming a two-dimensional web. A common form of the bridging nitrate group in the above is as an O,O'-NO3-O'.O '' bis-chelate, the pair of the bis-oxygen chelates having a common oxygen atom. (c) 2005 Elsevier B.V.
