“…In 1, the Pb atom is hexacoordinated with three carboxylate oxygen atoms from two distinct aic ligands, and three nitrogen atoms donors from two ctpt ligands, forming distorted [PbN 3 O 3 ] pentagonal-bipyramidal geometry. The bond distances of Pb-O in 1 are from 2.507(3) to 2.712(4) Å , and those of Pb-N bond distances fall in the 2.584(3)-2.736(4) Å range, which are similar with the values reported [8,[15][16][17]. As shown in Fig.…”

One coordination polymer [Pb(ctpt) 2 (aic)Á3H 2 O] n (1) [ctpt = 2-(4-Chloro-phenyl)-1H-1,3,7,8-tetraaza-cyclopenta[l]phenanthrene, aic = 5-Aminoisophthalic carboxylate] has been synthesized by hydrothermal reaction system and characterized by elemental analysis, thermogravimetric (TG) analysis, infrared spectrum and single-crystal X-ray diffraction. Complex 1 crystallizes with an N-donor chelating ligand and an aromatic dicarboxylate linker. Single-crystal X-ray diffraction reveals that 1 exhibits one-dimensional (1D) chain structure, and N-HÁÁÁO hydrogen bonds lead the 1D chain structure to 2D layer framework. TG analysis shows clear courses of weight loss, which corresponds to the decomposition of different ligands. The photoluminescence properties of the coordination polymer have also been investigated.

“…The N(O)-Pb-O(N) angles range are from 74.6(3)°to 150.9(3)°. The bond distances of Pb-O in complex 2 are from 2.427(8) to 2.660(8) Å, and those of Pb-N bond distances fall in the 2.550(9)-2.675(9) Å range, which are similar with the values reported[18][19][20][21]. The average bond of Pb-O is 2.560 Å, smaller than the average bonds of Pb-N (2.613 Å), which suggests that the…”

“…The HM based on the Pb complex demonstrated more intense PL. The Pb complexes with similar ligands had been described in [12][13], but the spectral-luminescent properties of these compounds had not been studied. The Pb-complex formation was confirmed by PL peak's positions which cannot be attributed to transitions between the levels of the individual ligands [14] or Eu 2+ ion PL in a glass [15].…”

Hybrid materials were synthesized using a high temperature reaction. We used 80PbF 2 Keywords hybrid materials, photoluminescence, europium coordination compounds IntroductionHybrid materials (HM) based on metal-organic phosphors and inorganic glasses are promising materials for developing new light emitting devices [1][2][3]. Organic luminescent materials are highly efficient under optical and electric excitation. However, most of them are extremely unstable in air and need protection. The embedding of organic materials into transparent matrices may solve the degradation problem and lead to the manufacturing of new materials. Inorganic glass matrices are stable at higher temperatures than organic polymers, lacquers and compounds and their thermal expansion coefficients are less than those of organic matrices. In general, glasses are characterized by a high hardness and chemical resistance, as well as a resistance to radiation, especially UV.In our previous research concerning on the fabrication of bulk and film hybrid materials, we considered boron oxide [2-3] as a glass matrix. However, boron oxide is not an ideal candidate for application as a glass matrix: its melt viscosity at 400-500 °C is very high (~2×10 4 Pa*s), and its chemical resistance is insufficient. We made glasses in the PbF 2 -B 2 O 3 system in the 25-80 mol% PbF 2 composition range [4][5]. These glasses have lower melting temperatures and viscosity index. Our latter research dealt with HM based on PbF 2 -B 2 O 3 glass and Eu(NTA) 3 (Phen) [6] demonstrated a possibility to fabricate transparent and stable glassy HM's.
