Abstract Metal: ligand complexes are crystallized from reaction mixtures of equimolar amounts of 4-cyano-3,6-bis(2-pyridyl)pyridazine 2 or 4-(4-bromophenyl)-3,6-bis(2-pyridyl)pyridazine 3 and silver(i) triflate. In [Ag2(2)(2)](2+), the two ligands adopt a head-to-tail arrangement, while a head-to-head motif is confirmed for the solid state structure of [Ag2(3)(2)](2+). In solution, one ligand environment is observed in each case. Silver(i) reacts with 1,3,5-tris3,6-bis(2pyridyl) pyridazin-4-yl benzene 4 to give highly insoluble powders. The single crystal structures of the pseudopolymorphs (4)center dot Et2O and 2(4)center dot 2MeCN center dot H2O are reported; in each structure, the ligand adopts the same conformation, derived from a C-s rather than C-3v model structure.
