## Abstract Hydrothermal reactions of Cd^II^, Co^II^, and Mn^II^ with the mixed ligands 3,4‐pyridinedicarboxylate (pydc), 1,3‐bis(4‐pyridyl)propane (bpp), or 1,2‐bis(4‐pyridyl)ethane (bpe) gave crystals of {[Cd(pydc)(bpp)]·0.5H~2~O}~__n__~ (1), {[Co(pydc)(H~2~O)(bpe)~0.5~]·0.5H~2~O}~__n__~ (2), and
We have been engaged in a study of light-induced cis-traus isaaerization and rearraoge--ments of the stilbazoles and bis-pyridyl-ethylenes, nitrogen containing analogs of stilbene.
In the title compound, C 12 H 8 N 4 OÁC 3 H 4 O 4 , a single O-HÁ Á ÁN hydrogen bond links the two molecules. In addition, C-HÁ Á ÁO and C-HÁ Á ÁN hydrogen bonds link these units into a two-dimensional framework.
The title complex, 2,5-di-4-pyridyl-1,3,4-oxadiazole-hydroquinone (1/1), C 12 H 8 N 4 OÁC 6 H 6 O 2 , crystallized from a solvent mixture of methanol and water. O-HÁ Á ÁN hydrogen bonds link the molecules to give a chain structure.
