Source of materialThe mixture of H0CI3 · 6H2O (0.2 mmol) and W-p-acetamidobenzenesulfonylglycine acid (abglyH2, 0.6 mmol), was stirred into 15 ml aqueous solution. Then the pH was adjusted to 5 with 1 M NaOH. Then 3 ml ethanol solution of 4,4-bipyridine (0.2 mmol) was added. The reaction mixture was heated on a water bath for 10 hours at 70° and filtered. Colorless crystals were obtained after 20 days.
DiscussionIn the past few years, the design and synthesis of metal organic materials have attracted increasing attention due to their potential applications in the field of optics, electronics, catalysis and magnetism [1][2][3][4][5][6]. Metal ions can be found as isolated clusters or chains which are connected to each other by the linkers. Organic carboxylates or N-donor ligands have been widely used in construction of coordination polymers containing transition metals. In contrast to the well-investigated transition metal system, the lanthanide coordination polymers have been less studied [7][8][9]. The lanthanide ions, with their high and variable coordination numbers, flexible coordination environments and luminescence properties, provide unique opportunities for discovery of unusual
