“…[23,24] Preparation of [Re(Ph 2 bpy)(CO) 3 These salts were prepared by a procedure similar to that reported in the literature. [6,7] In a typical experiment, [Re(CO) 5 Cl] (181 mg, 0.50 mmol) and 4,4Ј-diphenyl-2,2Ј-bipyridine (154 mg, 0.50 mmol) were heated at reflux in toluene (20 mL) for 1 h. It was cooled and then precipitated with hexane (40 mL).…”

pH‐Induced Luminescence Changes of Chromophore‐Quencher Tricarbonylpolypyridylrhenium(I) Complexes with 4‐Pyridinealdazine

The new chromophore-quencher tricarbonylrhenium(I) complexes [Re(4,4Ј-X 2 -bpy)(CO) 3 -salts and characterized by spectroscopic, electrochemical, and photophysical techniques. In contrast to previously reported species with X = Me or H, these complexes emit at room temperature in CH 3 CN. The recovery of luminescence can thus be ascribed to the change of energy levels induced by adding electron-withdrawing substituents to the 2,2Ј-bipyridine ring, since the emissive Re II (X 2 bpy -) excited state becomes much lower in energy than the Re II (PCA -) non-emissive excited state. For the mononuclear and symmetric dinuclear rhenium(I) complexes with X = CO 2 Me, consecutive

“…Pyridine-4-ylmethylidene) hydrazine-1-1-ylidene]methyl]pyridine was synthesized from the condensation pyridine-4-carboxaldehyde with hydrazine [4,5]. The Schiff base (0.001 mol), cadmium nitrate (0.001 mol) and anthracene-9-carboxylic acid (0.002 mmol) were loaded into a convection tube along with several drops of triethylamine; the tube was filled with methanol kept at 333 K. Crystals were collected from the side arm after several days; one type has a light yellow and the other a dark yellow color.…”

“…pyridine itself exists as a flat, centrosymmetric molecule [4,5] whose two aromatic donor sites are each capable of binding to a metal center to generate a chain motif, as exemplified by the cadmium nitrate adduct [6]. The present study was initiated to explore other adducts of cadmium bis(anthracene-9-carboxylate) as the compound forms adducts with other N-heterocyclic ligands: for example, the 2,2´-bipyridine and 1,10-phenanthroline adducts are both water-bridged dimers.…”

In the refinement of the crystal structure of [Cd(C 12 H 10 N 4 )(C 15 H 9 O 2 ) 2 (CH 3 OH)]·0.5H 2 O·CH 3 OH, the lattice water molecule was not located by difference Fourier synthesis but was instead deduced by using SQUEEZE owing to severe disorder of the water molecule in the otherwise ordered crystal structure. Similarly deduced were the two symmetry-independent methanol molecules in [Cd (C 12 H 10 N 4 ) 1.5 (C 15 H 9 O 2 ) 2 ]·CH 3 OH. The first coordination polymer adopts a chain motif and the second a layer motif; for both, the N-heterocycle functions as a bridge to connect adjacent metal atoms. The solvent molecules are presumed to reside in voids, which are themselves connected into channels. The crystallographic program Crystal Explorer was used in the illustration of the channels. Позицијата на молекулата на вода при уточнувањето на кристалната структура на [Cd(C 12 H 10 N 4 )(C 15 H 9 O 2 ) 2 (CH 3 OH)]·0.5H 2 O·CH 3 OH не е лоцирана со диферентната Фуриеова синтеза, туку е определена со помош на SQUEEZE, поради изразената несреденост на молекулата на вода во инаку средената кристална структура. На сличен начин се дефинирани и позициите на двете симетриски независни молекули на метанол во [Cd(C 12 H 10 N 4 ) 1.5 (C 15 H 9 O 2 ) 2 ]·CH 3 OH. Првиот координационен полимер гради синџирест мотив, а вториот слоевит мотив, при што за обата N-хетеропрстенот игра улога на мост кој ги поврзува соседните метални атоми. Молекулите на растворувачите се сместени во празнините, формирајќи преку меѓусебно поврзување посебни канали. За илустрирање на каналите е користена кристалографската програма Crystal Explorer.

A new tin complex, [l-(4-bpdb){Me 2 Sn(cupf) 2 } 2 ] (1), was prepared by reacting dimethyltin(IV) dichloride, with 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene (4-bpdb) and cupferron in a fast and facile process. The complex was fully characterized based on its 1 H and 13 C NMR, IR, and UV spectra and elemental analysis. The nanostructure of the prepared compound was synthesized by the sonochemical method. The new nanostructure was characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), IR spectroscopy and elemental analysis. Thermal stability of single crystalline and nanosize samples of the prepared compound was studied by thermal gravimetric and differential thermal analysis. The prepared complexes, as bulk and as nanoparticles, were utilized as a precursor for preparation of SnO 2 nanoparticles by direct thermal decomposition at 600°C in air. The morphology and size of the SnO 2 nanoparticles were determined by scanning electron microscopy, XRD and IR spectroscopy and the results showed that particle size of the SnO 2 nanoparticle depend on the initial particles size of 1. Photoluminescence properties of the nanostructured and crystalline bulk of the prepared complex and SnO 2 nanoparticles core of them were investigated.
