Copper- and Silver-perrhenate Hybrids

77 Layered Perrhenate and Vanadate Hybrid Solids On the Utility of Structural Relationships 

For the purposes of this discussion the focus here will be primarily on the pillared layered [Cu2(pzc)2(H20)2Re04] structure, which has served as an illustrative basis for several follow-up syntheses and new structures. 

The subsequent heterometallic perrhenate structures, seen in the sections below, reveal the utility of this assignment for forming structural relationships. 

As no simple copper-perrhenate salts previously existed to serve as a model for structural relationships to [Cu2(pzc)2(H20)2Re04], our attention turned to the syntheses of the isoelectronic silver-perrhenate systems. Shortly after an analysis of the structure above, a synthesis of the new pyrazine-pillared (=pyz) AgRe04(pyz) solid was found [30], and is shown in Fig. 17.3 alongside the re-
