Two new isomeric complexes, namely {[Cu(fum)(tpy)] · 5H2O}n (1) and [Cu2(fum)2(tpy)2] · 4H2O (2), have been synthesized simultaneously from the reaction of Cu(fum) with tpy (where fum = fumarate, tpy = 2,2′:6′,2″-terpyridine) under mild condition. The crystal structures of complexes were determined by X-ray single-crystal diffraction. Complex 1 stabilizes in an unusual 1D water tape notated T4(2)10(2), which is directed by two chiral helical water chains; binuclear complex 2 represents a complicated (6, 3)-connected framework via supramolecular interactions. Additionally, complex 1 exhibits weak ferromagnetic behavior.
Two complexes {[Cu(fum)(tpy)] · 5H2O}n (1) and [Cu2(fum)2(tpy)2] · 4H2O (2) have been synthesized upon the reaction of [Cu(fum)] with tpy (where fum = fumarate, tpy = 2,2′:6′,2″-terpyridine) in methanol–water solution. The crystal structure of 1 contains an unusual infinite 1D water cluster, notated as T4(2)10(2), which is directed by two independently H-bonded chiral helical water chains. And complex 2 shows a 14-membered macrocycle binuclear unit and a complicated (6, 3)-connected framework via H-bonded interactions.Figure optionsDownload as PowerPoint slide
