1,4-(Pyridazin-4-yl)benzene (bpph), a new N-donor tetradentate ligand, was prepared by inverse electron demand cycloaddition reacting 1,4-diethynylbenzene and 1,2,4,5-tetrazine. In combination with Cu(i) and Ag(i) ions, it affords coordination framework topologies that were dominated by assembly of dinuclear metal-pyridazine "secondary building blocks" [M2(μ-pdz) 2] supporting further polymeric connectivity. In structures [Cu 2(bpph)(CH3CN)2{S2O6}] (1) and [Ag6(bpph)3(H2O)6{C 6H4(COO)2}2]C6H 4(COO)2·4H2O (8) interconnection of the dinuclear nodes occurs with anionic dithionate and isophthalate bridges, while [Ag2(bpph){C6H5CO2} 2]·2H2O (7) adopts a linear chain structure incorporating disilver(i) pyridazine units and terminal benzoate anions. [Cu4(bpph)5](BF4)4·4CHCl 3 (2) has a 3D supramolecular structure involving polycatenation of the 2D "bilayer" metal-organic topologies built up of five-connected dinuclear nodes. Frameworks of [Ag(bpph){NO3}]·CHCl 3 (3) and [Ag(bpph){C2F5COO}] (5) exist as 2D square-grids nets supported with sets of tetra- and bidentate bipyridazine bridges, while closely related [Ag4(bpph)3{CF 3COO}4]·CH3CN (4) is a 1D "ladder" polymer. The three-fold interpenetrated 3D diamondoid framework of [Ag4(bpph)3{CH3SO 3}4]·2CHCl3 (6) was based upon more complicated tetranuclear nodes [Ag4(μ-pdz)4(pdz) 2].
