Abstract

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 ₃(μ ³-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 ₃(μ ³-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.
