2,11-dithia[3.3]paracyclopane; perfluoro-dicarboxylate; silver(I) coordination polymer; metal-organic complex

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 [(CF(2))(n)(COOAg)(2), n = 2], a 1D chain of [Ag(4)(dtpcp)(3-) (C(2)F(4)(CO(2))(2))(2)]center dot 2CH(3)OH (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 [(CF(2))(n)(COOAg)(2), n = 3] produces a 3D structure with composition of [Ag(2)(dtpcp)(C(3)F(6)(CO(2))(2))] (2), in which the disilver(I) hexafluoroglutarates connect with each other to form a ID S-shape chain and dtpcp ligands bridge such chains to give a 3D internet. With disilver(I) octafluoroadipate [(CF(2))(n)(COOAg)(2), n = 4], 2D porous sheets of [Ag(2)(dtpcp)(2)(C(4)F(8)(CO(2))(2))]center dot 2mesitylene (3) are formed. In polymer 3 four dtpcp and two octafluoroadipates are linked together by silver(l) ions to give a cavity in which two guest mesitylene molecules are located.
