A two-dimensional bilayered Cd^II coordination polymer with a three-dimensional supra­molecular architecture incorporating 1,2-bis­(pyridin-4-yl)ethene and 2,2′-(diazene­diyl)di­benzoic acid

The cadmium complex prepared by reaction of Cd(OAc)₂·2H₂O with 2,2′-(diazene­diyl)di­benzoic acid and 1,2-bis­(pyridin-4-yl)ethene possesses a two-dimensional bilayered structure with a 3⁶4¹³6² topology.

A three-dimensional Zn^II coordination framework: poly[[[mu]₂-(E)-1,2-bis(pyri­din-4-yl)ethene][[mu]₄-(E)-2,2'-(diazene-1,2-diyl)dibenzoato][[mu]₂-(E)-2,2'-(di­azene-1,2-di­yl)dibenzoato]dizinc(II)]

The title zinc(II) complex, prepared by the reaction of Zn(OAc)₂·2H₂O with 2,2'-(diazene-1,2-diyl)di­benzoic acid and 1,2-bis­(pyridin-4-yl)ethene in MeOH/H₂O at 393 K, possesses a three-dimensional framework with a 4⁶6⁴ topology. Powder X-ray diffraction and solid-state photoluminescent properties were also measured.

A three-dimensional Pb^II coordination framework: poly[[[mu]₄-(E)-2,2'-(diazene-1,2-di­yl)dibenzoato]di­methanol­lead(II)]

A lead(II) complex has been prepared by reaction of Pb(OAc)₂·2H₂O (OAc is acetate) with 2,2'-(diazene-1,2-di­yl)di­benzoic acid and 4,4'-bi­pyridine in MeOH-H₂O at 363 K. Single-crystal X-ray diffraction analysis reveals that the complex possesses a three-dimensional framework with a 4¹²6³ topology.

A helical zinc(II) coordination polymer assembled from 1,3-bis[(pyridin-3-yl)meth­oxy]benzene and benzene-1,4-di­carb­oxy­lic acid

In a one-dimensional Zn^II coordination polymer incorporating benzene-1,4-di­carboxyl­ate, aqua and 1,3-bis­[(pyridin-3-yl)meth­oxy]benzene ligands, (aqua)O-H...N hydrogen-bonding inter­actions induce the formation of one-dimensional helical chains which are inter­linked through (aqua)O-H...O hydrogen-bonding inter­actions, producing two-dimensional corrugated sheets.
