abstract

  • Hydrothermal reactions of cobalt or nickel sulfate with the appropriate substituted tetrazole yielded a series of compounds of the M(II)/tetrazolate/ sulfate family. While the parent compound [Co(prztet)2 (H 2O)2]0.5H2O (10.5H 2O; prztet = pyrazinetetrazolate) is molecular, the remaining materials exhibit extended structures. Thus, [Co2(4-pyrtet)(SO 4)(OH)(H2O)]1.5H2O (21.5H 2O), [Co3F2(SO4)(3-pyrtet) 2 (H2O)4] (4) and [Ni3F 2(SO4)(3-pyrtet)2(H2O)4] (5) are two-dimensional, in contrast to [Co4(prztet)6 (SO4)(H2O)2] (3) and [Ni5(3-pyrtet) 4(SO4)2(OH)2(H2O) 2]0.5H2O (60.5H2O) which are three-dimensional (3-pyrtet = 3-pyridinetetrazolate; 4-pyrtet = 4-pyridinetetrazolate). The sulfate-containing phases exhibit a variety of cluster-based secondary building units: variants of the common trinuclear motifs in 2, 4 and 5, a tetranuclear cluster core in 3, and a pentanuclear building block in 6. The sulfate ligands adopt monodentate and 2-, 3- and 4-bridging modes in the structures. 2012 Elsevier Ltd. All rights reserved.
