Solvent-Dependent Networking of O2S2-Macrocycle with Silver Perchlorate into One- and Two-Dimensional Coordination Polymers

The solvent-dependent double-stranded one-dimensional (1-D) coordination polymer [Ag 2 L 2 (ClO 4 ) 2 ] n ( 1 ) and another 1-D polymer {[Ag 2 L 2 (CH 3 CN)]·2ClO 4 } n ( 2a ) with the shape of a cut of tube along the long axis were obtained in the reactions of a 16-membered O 2 S 2 -macrocycle L with silver(I) perchlorate in DCM/MeOH and CH 3 CN, respectively. Time-dependent crystallization experiments unambiguously show that 2a is a kinetic product and transforms into a thermodynamically more stable [Ag L ClO 4 ] n ( 2b ) with a two-dimensional square-grid structure.
