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

Abstract

The solvent-dependent double-stranded one-dimensional (1-D) coordination polymer [Ag2L2(ClO4)(2)](n) (1) and another 1-D polymer {[Ag2L2(CH3CN)]center dot 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 O2S2-macrocycle L with silver(1) 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.
