The reactions of the p-xylene-bridged and methylene-bridged bipyrazolyl ligands 1,4-bis[(3',5'-dimethyl-1H-pyrazole-4'-yl)methylene]benzene (xdpH(2)) and bis[(3',5'-dimethyl-1H-pyrazole-4'-yl)]methane (mdpH(2)) with the appropriate copper salt have provided eight unique members of the Cu/bipyrazole/X system with X = Cl, Br, I and SO42. The anionic component of [Cu(xdpH(2))(H2O)]Cl center dot H2O (1 center dot H2O) acts as a simple charge-compensating counterion. In contrast, the anionic units of [Cu(xdpH(2))Cl-2]center dot 2DMF (2 center dot 2DMF), [Cu(xdpH(2))Cl-2(DMF)]center dot DMF (3 center dot DMF), [Cu-2(xdpH(2))(2)Br-2] (4), [Cu(mdpH(2))Br-2] (5), [Cu-4(xdpH(2))(4)I-4] (6), [Cu-2(xdpH(2))(2)(SO4)]center dot H2O (7 center dot H2O) and [Cu-2(xdpH(2))(2)(SO4)]center dot 2H(2)O (8 center dot 2H(2)O) are involved in bonding to the copper sites. Compounds 1, 4, and 6-8 contain Cu(I) sites while compounds 2, 3, and 5 are polymers of Cu(II). Compounds 1-5 and 7 are one-dimensional, while 8 is two-dimensional and 6 is three-dimensional. Considering the {Cu4I4} clusters of 6 as nodes, the structure is a fivefold interpenetrated framework with individual networks adopting the common {3(3).12(3)} topology in Schlafli notation.
