The bis(methylthio)methane building block was combined with AgX salt where X are weakly or noncoordinating counteranions (X = CF 3 SO 3 − ( 1 ), PF 6 − ( 2 ), SbF 6 − ( 3 ) and BF 4 − ( 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 C 2; a  = 17.3226(2) Å; b  = 9.2820(1) Å; c  = 29.726(3) Å; β  = 93.726(1)°; V  = 4787.59(9) Å 3 ; Z  = 4. ( 2 ) Monoclinic C 2/c; a  = 8.2468(4) Å; b  = 19.101(1) Å; c  = 10.1381(5) Å; β  = 107.065(2)°; V  = 1526.7(1) Å 3 ; Z  = 4. ( 3 ) Monoclinic C 2/c; a  = 13.2985(4) Å; b  = 16.1208(4) Å; c  = 8.9804(3) Å; β  = 95.883(2)°; V  = 1915.1(1) Å 3 ; Z  = 4. ( 4 ) Monoclinic C 2/c; a  = 16.7916(9) Å; b  = 9.1090(4) Å; c  = 22.670(1) Å; β  = 99.676(4)°; V  = 3418.2(3) Å 3 ; Z  = 4. The coordination polymer 1 forms channel-like 3D-cationic framework in which the trifluoromethanesulfonate anions are located. The octahedral counteranions, PF 6 − ( 2 ) and SbF 6 − ( 3 ), allow the formation of similar cationic cross-linked one-dimensional coordination polymers. Coordination polymers 2 and 3 have hexagonal packing. The tetrahedral counteranion BF 4 − ( 4 ) gives rise to cationic layer-like coordination network where the tetrafluoroborate anions are inserted between those sheets. Graphical Abstract 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 = CF 3 SO 3 − ( 1 ), PF 6 − ( 2 ), SbF 6 − ( 3 ) and BF 4 − ( 4 )). Those metallosupramolecular compounds have been characterized by elemental analysis, NMR spectroscopy, IR spectroscopy and X-ray crystallography.
