Supramolecular architecture of silver(I) coordination polymers containing polydentate N-donor ligands

The reaction of the polydentate N-donor ligands bmtz, H2bmtz, and bptz with various silver salts was investigated. New 1D coordination polymers [Ag2(bmtz) (ClO4)]ClO4 (1), [Ag(bmtz)]ClO4·MeCN (2), [{Ag(tcm)}2(H2bmtz)(MeCN)] (3) and [Ag(bptz)(NO3)] (5), and 2-D sheet structures, [{Ag(tcm)}2bmtz] (4), were synthesized. The structures are built up through the combination of coordination bonds, hydrogen bonding, Ag–π, π–π, and anion–π interactions to generate new supramolecular architectures. The supramolecular structure of the protonated amine salt [H2bptz](NO3)2 (6) is also described.
