Abstract

The reactions of the p-xylene-bridged and methylene-bridged bipyrazolyl ligands 1,4-bis[(3',5'-dimethyl-1H-pyrazole-4'-yl)methylene]benzene (xdpH2) and bis[(3',5'-dimethyl-1H-pyrazole-4'-yl)]methane (mdpH2) with the appropriate copper salt have provided eight unique members of the Cu/bipyrazole/X system with X = Cl-, Br-, I- and SO4 2-. The anionic component of [Cu(xdpH2)(H2O)]Cl·H2O (1·H2O) acts as a simple charge-compensating counterion. In contrast, the anionic units of [Cu(xdpH2)Cl2]·2DMF (2·2DMF), [Cu(xdpH2)Cl2(DMF)]·DMF (3·DMF), [Cu2(xdpH2)2Br2] (4), [Cu(mdpH2)Br2] (5), [Cu4(xdpH2)4I4] (6), [Cu2(xdpH2)2(SO4)]·H2O (7·H2O) and [Cu2(xdpH2)2(SO4)]·2H2O (8·2H2O) 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 {33.123} topology in Schlafli notation.
