Popis: The bis(methylthio)methane building block was combined with AgX salt where X are weakly or noncoordinating counteranions (X = CF3SO3 − (1), PF6 − (2), SbF6 − (3) and BF4 − (4)) in order to form cationic metal–organic frameworks where the anions only counterbalance the charge of the networks. The crystallographic data of those complexes are: (1) Monoclinic C2; a = 17.3226(2) A; b = 9.2820(1) A; c = 29.726(3) A; β = 93.726(1)°; V = 4787.59(9) A3; Z = 4. (2) Monoclinic C2/c; a = 8.2468(4) A; b = 19.101(1) A; c = 10.1381(5) A; β = 107.065(2)°; V = 1526.7(1) A3; Z = 4. (3) Monoclinic C2/c; a = 13.2985(4) A; b = 16.1208(4) A; c = 8.9804(3) A; β = 95.883(2)°; V = 1915.1(1) A3; Z = 4. (4) Monoclinic C2/c; a = 16.7916(9) A; b = 9.1090(4) A; c = 22.670(1) A; β = 99.676(4)°; V = 3418.2(3) A3; Z = 4. The coordination polymer 1 forms channel-like 3D-cationic framework in which the trifluoromethanesulfonate anions are located. The octahedral counteranions, PF6 − (2) and SbF6 − (3), allow the formation of similar cationic cross-linked one-dimensional coordination polymers. Coordination polymers 2 and 3 have hexagonal packing. The tetrahedral counteranion BF4 − (4) gives rise to cationic layer-like coordination network where the tetrafluoroborate anions are inserted between those sheets. Four new silver(I)—coordination polymers have been obtained from the combination of bis(methylthio)methane building block and AgX salt where X are weakly or noncoordinating counteranions (X = CF3SO3 − (1), PF6 − (2), SbF6 − (3) and BF4 − (4)). Those metallosupramolecular compounds have been characterized by elemental analysis, NMR spectroscopy, IR spectroscopy and X-ray crystallography.
