The reaction of 1,2-bis(4-pyridyl)ethane-N,N'-dioxide (bpeado) with metal perchlorate or tertraphenylborate yields coordination frameworks with different structurse, [Mn(bpeado)(3)][ClO4](2) (1), [Cu(bpeado)(2)(H2O)(2)][ClO4](2) center dot bpeado (2) and [M(bpeado)(3)][B(Ph)(4)](2) [M Mn 3 and Co 4]. Compound 1 is based-on octahedrally coordinated MnO6 centers bound through six oxygen atoms from six separate anti-bpeado ligands with 3-fold interpenetrated alpha-Po-type structure. 2 has two-dimensional (4,4) layers bridged by four separate anti-bpeado molecules and the layers were further connected by hydrogen bonding between the coordination water molecules and the intercalated bpeado, forming a 2-fold interpenetrated alpha-Po-type network. Compounds 3 and 4 are isostructural and comprised of non-interpenetrating rectangular (4,4) layers bridged by both anti- and gauche-bpeado.
