“…These are attached to three Y 3+ ions, and a three-dimensional network is built providing large channels which are occupied by free nitrate ions (Figure ). Other hydroxide-rich oxide-containing rare-earth nitrates are the compounds {[M 6 O](OH) 8 (H 2 O) 12 (NO 3 ) 6 }(NO 3 ) 2 · x H 2 O. − Analogously to the related basic perchlorates, they contain as the characteristic structural feature an oxide-centered [OM 6 ] octahedron with each of its triangular faces capped by an OH - ion. Furthermore, 12 H 2 O molecules are bridging the 12 edges of the octahedron.…”

Mathias S. Wickleder was born in Bergen, Germany, in 1965. He received his Dr. rer. nat. degree at the University of Hannover under the direction of Professor G. Meyer in 1994. Thereafter he joined the group of Professor H. U. Gu ¨del, Bern, Switzerland, as a postdoctoral fellow for two years. In 2000 he finished his Habilitation at the Institute for Inorganic Chemistry in Cologne. His research interests include the structural chemistry and thermal behavior of rare-earth and transition-metal compounds with complex anions.

“…The thermal behavior of various solid pentanitrato complexes with the general formula M' ¸n ''' (NO ) ) nH O (M"alkaline metal, silver, or ammonium ion) has been described in earlier studies (1)(2)(3)(4)(5)(6). Their decomposition processes have been found complex and dependent on the experimental conditions used.…”

“…Their decomposition processes have been found complex and dependent on the experimental conditions used. In particular, a complete interpretation of the thermal decomposition of Rb Ce(NO ) ) 4H O (1), (NH ) Ce(NO ) ) 4H O (5), and Ag Ce(NO ) ) H O (6), based on the use of temperature-dependent X-ray powder diffraction (TDXD) and conventional thermal analysis, has been reported. All phases formed during the thermal treatment were identified and characterized from X-ray powder diffraction.…”

“…In comparison with the reported structure of Ag-Ln complexes, [43][44][45][46][47][48][49][50][51][52][53][54][55] the main structural characteristic for complex 1 is that the carboxyl oxygen atoms act as a single-atom bridge to coordinate to metal ions (bridging Eu and Ag or Ag and Ag). This causes the central metal ions to be near each other in complex 1: the separations of EuÁ Á ÁAg are 3.73 (EuÁ Á ÁAg1) and 3.75 (EuÁ Á ÁAg2) A ˚(Fig.…”

“…We have so far only found ten or so reports on Ag-Ln complexes to our best knowledge. [43][44][45][46][47][48][49][50][51][52][53][54][55] In those Ag-Ln cases, from a structural point of view, the ligands bridging the Ln(III) and Ag(I) ions are focused on aromatic organic molecules with both N-and O-donor atoms, such as pyridine-carboxylato, dtpa (diethylenetriaminepentaacetato), imidazole-carboxylato as well as with acetato, oxalato and 1,2-benzenedicarboxylato as co-ligands.…”

Synthesis and structure of a series of new luminescent Ag–Ln coordination polymers and the influence of the introduction of an Ag(i) ion on NIR luminescence from the Ln(iii) centre

A series of new Ag-Ln coordination polymers [LnAg 5 (bdc) 4 ] n (Ln = Eu (1); Yb (2); Er (3); Ho (4); H 2 bdc = 1,2-benzenedicarbolylic acid) has been synthesized by a hydrothermal method and characterized by single-crystal X-ray diffraction, elemental analysis, thermogravimetric analysis, IR spectra, UV-Vis-NIR absorption spectra and fluorescence spectra. X-ray structural investigations reveal that these polymers are isomorphous and exhibit a 2D layer structure formed by a coordination bond and weak metalÁ Á Ámetal interaction. Polymers 1-4 exhibit a characteristic emission corresponding to the Ln(III) ions in the near-infrared (NIR) region or in the visible region. Especially, the NIR emission bands of polymers 2-4 present evidently shift or splitting compared with the isolated Ln(III) ions due to formation of the Ag-Ln coordination polymer. In the Ag-Ln coordination polymer, the AgÁ Á ÁLn separation is much shorter (3.71-3.75 Å ), thus the d-orbital of the Ag(I) ion and f-orbital of the Ln(III) ion may interact and influence each other, which probably caused the inner levels of the Ag-Ln system to be tuned. This can have an important impact on the NIR emission band presenting shift or splitting, which can be confirmed by the UV-Vis-NIR absorption spectra. Solid 1 shows intense characteristic emissions of the Eu(III) ion in the visible region, which is attributed to sensitization from the ligands and Ag-block (Ag-ligand section).
