文摘

Transition metal complexes of the ligand 2,2鈥?bipyridine-4,4鈥?diamine (bpy4da) form three-dimensional (3D) hydrogen bonding networks with the [M(bpy4da)₃]²⁺ species, a hydrogen donor metallo-tecton with carboxylate counteranions as hydrogen bond acceptors within the complexes [[Ni(bpy4da)₃]路(Hbpc)(bpc)_0.5(dmf)_n, [Ni(bpy4da)₃].(bpc)(dmf)_n, and [Ni(bpy4da)₃]路(Htma)路4(dmf) where H₂bpc = biphenyl-4,4鈥?dicarboxylic acid, H₃tma = trimesic acid, and dmf = dimethylformamide. Terephthalate, on the other hand, bridges between Cu(II) centers in complexes [Cu₂(bpy4da)₄(tpa)]路2(NO₃)路5(dmf) and [Cu₂(bpy4da)₄(tpa)]路2(NO₃)路4.5(dmf)路(H₂O) (where H₂tpa = terephthalic acid) whose structures both feature different 3D hydrogen bonded networks. The crystal structures of hydrated [Cd(bpy4da)₃]路2Cl and [Co(bpy4da)₂(NO₃)]₂路2(NO₃)路4.5(dmf) are also reported.
