Silver(I) coordination polymers of 2,11-Dithia[3.3]paracyclophane and in situ Silver(I) perfluoro-dicarboxylates

Abstract

Coordination polymers of 2,11-dithia[3.3]paracyclopane (dtpcp) with in situ silver(I) perfluoro-dicarboxylates characterized by single crystal X-ray analysis are described. Their structures were found to strongly depend on the dicarboxylates. With disilver(I) tetrafluoro-succinate [(CF2)n(COOAg)2, n=2], a 1D chain of [Ag4(dtpcp)3- (C2F4(CO2)2)2]•2CH3OH (1) forms in which two silver(I) ions link with two dtpcp ligands to afford a four-numbered ring and disilver(I) tetrafluoro-succinates link such rings. Changing the silver salt to disilver(I) hexafluoroglutarate [(CF2)n(COOAg)2, n=3] produces a 3D structure with composition of [Ag2(dtpcp)(C3F6(CO2)2)](2), in which the disilver(I) hexafluoroglutarates connect with each other to form a 1D S-shape chain and dtpcp ligands bridge such chains to give a 3D internet. With disilver(I) octafluoroadipate [(CF2)n(COOAg)2, n=4], 2D porous sheets of [Ag2(dtpcp)2(C4F8(CO2)2)]•2mesitylene (3) are formed. In polymer 3 four dtpcp and two octafluoroadipates are linked together by silver(I) ions to give a cavity in which two guest mesitylene molecules are located. © 2009 SIOC, CAS, Shanghai, & WILEY-VCH Verlag GmbH & Co.
