A novel 2-D silver(I)-acyclic polyene coordination polymer assembled with linear unsaturated bridges

A novel 2-D silver(I) coordination polymer of 1,8-diphenylocta-1,3,5,7-tetr aene was synthesized, and characterized by X-ray single crystal analysis. R eaction of 1,8-diphenylocta-1,3,5,7-tetraene (dpot) with silver(I) perchlor ate at 60 degreesC afforded [Ag-2(dPot)(ClO4) (1). In this structure, silve r(I) adopts a distorted tetrahedral geometry and the dpot molecules link th e silver(I) ions in a trans-mu -tetra-eta (2) manner to generate 1-D chains with metallocyclophane motifs. Further, the silver(I) ions between the two neighboring chains are bridged by perchlorate groups to give a novel 2-D ( 3,4)-connected polymeric network with (4,6(2))(2)(4(2),6(2),8(2)) topology. Additionally, the main plane of the phenyl moiety makes an angle of 33.08 degrees with the topology through the polyene portion in 1, and thus the co ordination of silver(I) to dpot results in the distortion of the dpot molec ule. To the best of our knowledge, this is the first example of a silver(I) complex with acyclic polyene. (C) 2001 Elsevier Science B.V. All rights re served.
