A new high-dimensional architecture constructed from paradodecatungstate and [Cu(2-Hpzc)]2+ complexes
چکیده انگلیسی

A new compound, H4{[Cu3(2-Hpzc)2(H2O)4](H2W12O42)}·13H2O (1) (2-Hpzc = 2-pyrazinecarboxylic acid), was synthesized in conventional condition and characterized by elemental analyses, IR spectroscopy, thermal gravimetric analysis, X-ray powder diffraction (XRPD) and single X-ray diffraction. In the structure of compound 1, each paradodecatungstate anion acts as a quadridentate ligand coordinating to four Cu2+ cations through its terminal oxygen atoms to form a two-dimensional (2D) layer. The infinite [Cu(2-Hpzc)]2+ chains connect adjacent layers forming a three-dimensional (3D) architecture. There exist two kinds of channels with sizes of ca. 5.737 × 4.628 Å2 and 9.104 × 8.640 Å2 along the b and c directions, respectively. The magnetic behavior of 1 exhibits antiferromagnetic interaction.

A new compound with three-dimensional framework has been synthesized, which represents the first high-dimensional hybrids based on paradodecatungstate modified by [Cu(2-Hpzc)]2+ complexes.Figure optionsDownload as PowerPoint slide
