In this study, two coordination polymers were synthesized by using 3,6-dimethoxy-s-tetrazine(dmotz) and multiple silver salts (AgX; X= CF3SO3-, and ClO4-). In the 3D crystal structure of [Ag(dmotz)(CF3SO3)]n(1), an anion CF3SO3- resulted 1D linear chain network, and a use of ClO4- led a coordination polymer {[Ag(dmotz)](ClO4)}n (2) to form the 2D grid network. Interestingly, a structural transformation under mechanochemical condition from 1 to 2 was achieved due to the stronger anion-π interaction between 3,6-dimethoxy-s-tetrazine(dmotz) and ClO4-. However, the opposite transformation from 2 to 1 was not driven in spite of an excess of CF3SO3- anion. This presentation will provide an anion dependent structural transformation of coordination polymers under mechanochemical conditions and their X-ray 3D crystal structures.
