Abstract
Two new silver(I)–dithioether coordination polymers based on the self-assembly of the dithioether ligands L n−R = CH3–S(CH2) n S–CH3 (n = 1, 3) and AgX silver salts, where X = ClO4 − (1) and PF6 − (2), have been synthesized and characterized by single crystal X-ray diffraction and TGA. The crystallographic data of those complexes are: (1) Monoclinic P21/c; a = 16.5861(3) Å; b = 10.1048(2) Å; c = 15.7843(3) Å; β = 112.570(1)°; V = 2442.83(8) Å3; Z = 4. (2) Monoclinic P21/n; a = 8.6500(2) Å; b = 9.4053(2) Å; c = 24.0357(6) Å; β = 92.750(2)°; V = 1953.19(8) Å3; Z = 4. In both complexes, the dithioether building blocks propagated the silver(I) centers to build cationic lamellar coordination polymers, while ClO4 − and PF6 −, which were sandwiched between silver-ligand sheets, counterbalance only the charge of the networks. The thermogravimetric investigation reveals that those complexes decompose in a single step respectively to metallic silver and silver salt.
Index Abstract
Two new silver(I)–dithioether coordination polymers, obtained from the self-assembly of dithioether ligands and AgX salts with noncoordinating counteranions (X = ClO4 − and PF6 −), were characterized by X-ray crystallography and thermogravimetric analysis (TGA).
