Abstract
Yellow prismatic nanoparticles of the supramolecular coordination polymer (SCP) [Cu-6(CN)(7)(C6H12N4)(2)(OH3)], 1 were obtained by the reaction of K-3[Cu(CN)(4)] and hexamethylenetetramine (hmt) in presence of Me3SnCl at ambient conditions. The X-ray structure of 1 consists of many rhombic [(Cu)(2)A mu(3)-(CN)(2)] motifs which construct eight fused cyclic rings accommodating two hmt ligands. The copper atoms exhibit pseudo-tetrahedral configuration. The cyanide ligands create the bifurcated A mu(3)-CN bridges. The [(Cu)(2)A mu(3)-(CN)(2)] motifs causes expansion of the structure of 1 to three dimensions while extensive H-bonds play an essential role in packing structure. SCP 1 was used as an efficient heterogeneous catalyst for oxidative mineralization of acid blue-92 (AB-92), textile dye, with H2O2. The study aimed to investigate the efficiency of recycled the catalyst 1 and the mechanism of degradation of AB-92. The morphological feature of the SCP 1 as a catalyst before and after catalysis was examined by high resolution transmission electron microscope (TEM).
