Hydrothermal reactions of Cu(SO 4)•5H 2O with pyridyl- and pyrazine-substituted tetrazoles provided a series of materials of the Cu(II)/imine-tetrazolate/SO 4 2- class. [Cu 3(OH)(H 2O) 3(3-pyrHtet-O) 3(SO 4)] (1) (3-pyrHtet-O = 2-hydroxy-3-Hpyridyltetrazolate) is molecular and exhibits the common {Cu 33-OH)} 5+ core. In addition, the pyridyl group of the ligand has been hydroxylated to the to the 2-hydroxy-3-Hpyridyltetrazole form. While the two-dimensional [Cu 3(OH) 2(H 2O) 3(3-pyrtet) 2(SO 4)] (2) also contains the {Cu 33-OH)} 5+, the 3-pyrtet ligands (3-pyridyltetrazolate) project outward from the cluster core to link to adjacent clusters in forming the network connectivity. The two-dimensional (Me 2NH 2)[Cu(2-pyrtet)(SO 4)] (3) exhibits binuclear building units {Cu 2(2-pyrtet)} 2+ that link to adjacent units through the sulfato groups. In contrast, the pyrazinetetrazolate derivative, [Cu 4(pyrztet) 6(H 2O) 2(SO 4)] (4), is constructed from {Cu 4(tetrazolate) 6(H 2O) 2(SO 4)} n chains linked through the pyrazinetetrazolate ligands into a three-dimensional framework. The magnetic properties of the compounds reflect these structural characteristics.
