Synthesis and Structure of RhMg3 and Ir3Mg13

SYNTHESIS AND CRYSTAL STRUCTURE OF [Pph ] [WS (CUNCS) ] A. Taeb A. Beheshti and N.K. Javadi SYNTHESIS AND CRYSTAL STRUCTURE OF [Pph ] [WS (CUNCS) ]

The crystals of [WS (CuNCS) ] anion have been isolated from CH ,CI solution and examined by X-ray structural analysis as well as by IR spectroscopy. The unit cell is monoclinic with a= 14.3796(13), b= 18.039(1 I), c= 22.5956(23)& P= 96.053(8)', space group P2,/n (14), Z= 4. The crystal structure was refined by the least-squares calculations to a final R-value of 0.0398(Rw= 0.0443) for 2777 u...

SYNTHESIS, CHARACTERIZATION AND CATALYTIC BEHAVIOUR OF SPECIAL TYPE OF SILICO ALUMINO-PHOSPHATE WITH OPAL STRUCTURE

In this study a special type of silicoaluminophosphate with opal structure (Opal-SAPO) was prepared under microwave condition using tetraethylorthosilicate (TEOS), triethanolamine (TEA), aluminiumisopropoxid and phosphoric acid 85%. The product was characterized by X-ray diffraction (XRD), thermogravimetric (TGA) and Fourier Infrared Spectroscopy (FTIR).The crystalline product showed a good act...

SYNTHESIS AND STRUCTURE ELUCIDATION OF 1,2,4-TRIAZINO [4,3-b] 1,2,4-TRIAZINES, 1,2,4-TRIAZINO [3,4-C] 1,2,4-TRIAZINES AND 1,2,4-TRIAZINO [4,3-dl l,2,4-TRIAZINES

SYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]

The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...

Co-precipitation Synthesis of Zinc Oxide (ZnO) Nanoparticles by Zinc Nitrate Precursor

Nanostructured zinc oxide (ZnO) materials have received considerable interest from scientists due to their remarkable performance in electronics, optics and photonics. ZnO nanoparticles were synthesized by co-precipitation method. ZnO nanoparticles were synthesized using Zn(NO3)3 and K2CO3 precursors. The structure of the obtained product was confirmed by the powder X-ray diffraction (XRD) anal...
