7440-21-3 Mixed Carbide Al4SiC4: Preparation and Structural Data.

-
An addition of aluminum to SiC promotes its densification through the formation of a ternary carbide Al//4SiC//4. A method of preparation of this compound is proposed, and its composition formula has been determined. Al//4SiC//4 has a hexagonal structure, with lattice parameters a equals 3. 28 Angstrom and c equals 21. 72 Angstrom. Single crystals have been studied by X-ray diffraction, electronic microprobe, and optical microscopy. An epitaxial growth effect has been observed between Al//4SiC//4 and the carbide Al//4C//3, and the possible existence of a family of Al//4C//3(SiC)//n compounds is proposed. https://www.lookchem.com/CASDataBase_7440-21-3.htm

1023-17-2 Syntheses, structures, and catalytic activity in Friedel–Crafts acylations of substituted tetramethylcyclopentadienyl molybdenum carbonyl complexes

-
Reactions of the substituted tetramethylcyclopentadienes [C 5 HMe 4 R] [R?=? t Bu, Ph, CH 2 CH 2 C(CH 3 ) 3 ] with Mo(CO) 3 (CH 3 CN) 3 in refluxing xylene gave a series of dinuclear molybdenum carbonyl complexes [(η 5 -C 5 Me 4 R)Mo(CO) 3 ] 2 [R?=? t Bu (1), Ph (2), CH 2 CH 2 C(CH 3 ) 3 (3)], [(η 5 -C 5 Me t Bu)Mo(μ-CO) 2 ] 2 (4)], and [(η 5 -C 5 Me 4 ) t Bu] 2 Mo 2 O 4 (μ-O) (5)], respectively. Complexes 1–5 were characterized by elemental analysis, IR, 1 H NMR, and 13 C NMR spectroscopy. In addition, their crystal structures were determined by X-ray crystal diffraction analysis. The catalytic activities of complexes 1–3 in Friedel–Crafts acylation in the presence of o-chloranil has also been investigated; the reactions were achieved under mild conditions to give the corresponding products in moderate yields. https://www.lookchem.com/CASDataBase_1023-17-2.htm

7440-47-3 Influence of pulse plating on the crystal structure and orientation of chromium

-
Chromium deposits with various structures and orientations were prepared by pulse plating from a sulfate-catalyzed chromic acid solution and without formic acid addition. The influences of the puls duration, off-time, curent density, formic acid concentration, and plating time on the structure and orientation were studied by X-Ray diffraction and transmition electron microcsopy. https://www.lookchem.com/CASDataBase_7440-47-3.htm
