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 [Ag₂L₂(ClO₄)₂]_n (1) and another 1-D polymer {[Ag₂L₂(CH₃CN)]·2ClO₄}_n (2a) with the shape of a cut of tube along the long axis were obtained in the reactions of a 16-membered O₂S₂-macrocycle L with silver(I) perchlorate in DCM/MeOH and CH₃CN, respectively. Time-dependent crystallization experiments unambiguously show that 2a is a kinetic product and transforms into a thermodynamically more stable [AgLClO₄]_n (2b) with a two-dimensional square-grid structure.
