摘要

Solvothermal reaction of N,N'-Bis[(pyridin-3-yl)rnethyl]pyridine-2,5-dicarboxamide (L~1) as well as Zn(OAc)2 or Co(NO3)2 in methanol gave rise to two new 2D complexes [Zn(L~2)2]_n (1) and [Co(L~2)2]_n (2), in which in situ formation of an anionic ligand 5-((pyridin-3-yl)methylcarbamoyl)pyridine-2-carboxylate (L~2) was observed. Single-crystal structural analysis reveals that 1 and 2 are isostructural, and the 2D helical networks are assembled from two different-handed strands with shared the common metal atoms. Fluorescent and thermal properties of complexes 1 and 2 are also investigated.
