“…5 This series was completed in 2004 with the isolation of La(NO 2 ) 3 , as a coordination polymer. 6 Only six molecular nitrite complexes have been reported with REEs, namely [(Tp Me2,4-Et ) 2 Sm(NO 2 )], 7 [(C 5 H 5 ) 2 Yb(NO 2 )(THF)], 8 [Ln(L)(NO 2 )-(H 2 O)] (Ln = Sm, Eu, L = 2,2′-(biphenyl-4,4′-diylbis(oxy))diacetate), 9 10 From a structural point of view, the rational synthesis and the characterization of well-defined REEs nitrite complexes would therefore afford molecular models to better apprehend the redox chemistry of nitrogen oxides in lanthanide chemistry. Additionally, it has been recently shown that the nitrite anion NO 2 − behaves as an attractive one electron oxidant in the coordination sphere of uranium(III) and uranium(IV), to access uranium-oxo functionalities.…”

The coordination chemistry of the nitrite anion has been investigated with rare earth elements, and the resulting complexes were structurally characterized. Among them, the first homoleptic examples of nitrite complexes of samarium, ytterbium and yttrium are described. The coordination behavior of the nitrite ion is directly controlled by the ionic radius of the metal cation. While the nitrito ligand is stable in the coordination sphere of cerium(iii), it is readily reduced by SmI2.

Fourier transform infrared (FTIR) spectrum dielectric constant, e 0 , loss tangent, tan(d), electric modulus, M*, and ac conductivity, r ac , of pure polyvinyl alcohol (PVA) as well as La-, Gd-, and Er-PVA doped samples have been carried out. The dielectric properties have been studied in the temperature and frequency ranges; 300-450 K and 1 kHz-4 MHz, respectively. FTIR measurements reveal that La 3þ , Gd 3þ , and Er 3þ ions form complex configuration within PVA structure. Two relaxation processes, namely, q and a were observed in pure PVA sample. The first process is due to the interfacial or Maxwell-Wagner-Sillers polarization. The second one is related to the micro-Brownian motion of the main chains. For doped PVA samples, a-relaxation process splits into a a and a c . This splitting is due to the segmental motion in the amorphous (a a ) and crystalline (a c ) phases of PVA matrix. Electric modulus analysis was discussed to understand the mechanism of the electrical transport process. The behavior of ac conductivity for all PVA samples indicates that the conduction mechanism is correlated barrier hopping. V C 2012 American Institute of Physics. [http://dx

“…[1][2][3][4][5][6][7][8] As rigid ligands, aromatic carboxylic acids have been widely used to construct lanthanide complexes. 9,10 Lanthanide aromatic carboxylate complexes often show distinctive molecular structures because lanthanide ions have larger radii and higher variable coordination numbers than transitional metals, 11,12 and aromatic carboxylic acids have a variety of coordination modes.…”

A new coordination polymer {[Eu 2 (Cl 2 C 6 H 3 OCH 2 COO) 6 The crystal structure shows that the title complex forms one-dimensional chain structure by bridging 2,4-dichlorophenoxy acetic acid anions. Every centric europium(III) ion is coordinated with ten oxygen atoms from five 2,4-dichlorophenoxy acetic acid anions and two water molecules, giving a ten-coordinated distorted bicapped square antiprism geometry. The luminescent property and thermal stability of the complex are also studied.
