A new compound constructed from Keggin anions and Cu-5,6-diamino-1,10-phenanthroline complexes: synthesis,structure, and characterization |

Abstract: | A new inorganic–organic hybrid based on polyoxometalate, Cu2(daphen)2(H2O)4(PW11WVO40)]?·?6H2O (1) (daphen?=?5,6-diamino-1,10-phenanthroline), was synthesized hydrothermally and characterized by single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy, and thermal analysis. Single-crystal X-ray diffraction analysis reveals that in 1 the Keggin anion PW12O40]4? is tetradentate, linking four Cu(II)-daphen fragments with its four terminal oxygen atoms in a plane; Cu2+ is coordinated by two terminal oxygen atoms of two PW12O40]4? anions, two water molecules, and two nitrogen atoms of the phen ring of a daphen, forming a polymeric layer. The 3-D architecture of the compound is further formed via hydrogen bonds between these layers. The daphen is bidentate chelating and does not participate in formation of hydrogen bonds. Redox of 1 was examined. |
