Abstract
The hydrothermal reactions of various Cu(II) salts with 3- and 4-pyridinetetrazole and pyrazinetetrazole were exploited in the preparation of a series of Cu(II) and Cu(I) azolate materials. The parent copper/ pyridyltetrazole compositions are observed in the two-dimensional [Cu(3-pyrtet)2] (1), the reduced three-dimensional [Cu(4-pyrtet)] (2) and reduced two-dimensional [Cu(4-pyrtet)]·0.5DMF (3·0.5DMF) (Hpyrtet = pyridyltetrazole). The consequences of introducing coordinating anions are revealed in the structures of the one-dimensional [CuCl 2(4-Hpyrtet)]·0.5H2O (4·0.5H2O) and the two-dimensional [Cu2I2(4-Hpyrtet)] (5) and [Cu(acac)(4-pyrtet)] (7) (acac = acetylacetonate; H2en = ethylenediammonium cation). The pyrazinetetrazolate derivative [H 2en]0.5[CuCl2(prztet)] (Hprztet = pyrazinetetrazole) (6) is one-dimensional, but structurally distinct from the chain observed for 4.
