The reaction of pyrazine‐2‐carboxylate (pca) and bis(pyridine) derivatives, such as 4,4′‐bipyridine (bipy), 1,2‐bis(4‐pyridyl)ethylene (bpen), 1,2‐bis(4‐pyridyl)ethane (bpea), 1,3‐bis(4‐pyridyl)propane (bpp), and 4,4′‐azopyridine (azp), with zinc perchlorate gives supramolecules with grid and/or channel structures. The new complexes reported here are trans ‐[Zn(bipy)(pca)(H 2 O)]ClO 4 ·(EtOH) 0.5 ·(H 2 O) 0.5 ( 1 ), [Zn(μ‐bpen)(bpen)(pca)(H 2 O)]·ClO 4 ·2H 2 O ( 2 ), [Zn(bpea)(pca)]ClO 4 ·(EtOH) 0.5 ( 3 ), and [Zn(bpp)(pca)(MeOH)]ClO 4 ( 4 ). Their structures have been established by single‐crystal X‐ray diffraction. Some of these complexes contain voids with nanometer dimensions. Small molecules such as H 2 O, MeOH, and EtOH contained in these voids can be removed without destruction of the parental suprastructure. (© Wiley‐VCH Verlag GmbH & Co.
