A complex of N, N, N', N', -tetramethylated ethylenediamine, TMEDA, with CuCI is prepared. The crystal and molecular structure of this complex is characterized by a single-crystal X-ray diffraction study. The complex is found to contain [Cu (TMEDA) ] cation which is nearly tetrahedral and the [CuCI ) anion is linear which Cu lies on a center of symmetry. Crystals are monoclinic space grou...
N'-(2-hydroxy-3-methoxybenzylidene)-4-methylbenzenesulfonohydrazide (1) was prepared by the reaction of p-Toluenesulfonyl hydrazide and 2-hydroxy-3-methoxy benzaldehyde (1:1 molar ratio) in ethanol under reflux condition. The crystal structure of the compound was determined by X-ray crystallography. Crystal data for 1 at -100 K: space group C/2c with: a = 15.807(1) Å, b = 10.457(1) Å, c = 20.77...
Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration levels. X-ray diffraction (XRD) was used to investigate the films crystal structures. The results indicate that if the Co concentration is less that the Fe concentration, the cubic structure appears in the films, while the hexagonal structure dominates when the C...
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...
In the last decade, Calcium Titanate has been introduced as a bioceramic with acceptable mechanical and biological properties for orthopaedic implant applications. In this study, CaTiO3 nano-structure coating was produced by sol-gel dip-coating route for biomedical applications. Calcium nitrate and titanium isopropoxide were used as a precursor. After coating process, the specimen was subject...
