A new class of CVD precursors to metal borides: Cr(B3H8)2 and related octahydrotriborate complexes.
Treatment of CrCl3 with sodium octahydrotriborate, NaB3H8, affords a thermally unstable purple liquid thought to be a chromium(III) hydride of stoichiometry CrH(B3H8)2. This hydride converts rapidly at room temperature to the chromium(II) complex Cr(B3H8)2, which adopts a square-planar structure in which four hydrogen atoms form the coordination sphere of the chromium atom. This chromium(II) sp...
متن کاملBarium Diketonates as Precursors for HTSC Thin Films : Structure and Properties
Homoligand and mixed ligand barium diketonate complexes have been synthesized and characterized by X-ray structure determination. Homoligand complexes with dipivaloylmethane hexafluoroacetone and pivaloyltrifIuoroacetone have oligigomeric or polymeric structure. The mixed complexes with additional anionic ligands (ClOH-, Piv-) form pentanuclear complexes. The structures of the mixed ligand comp...
متن کاملReversible luminescent colour changes of mononuclear copper(i) complexes based on ligand exchange reactions by N-heteroaromatic vapours.
[CuCl(PPh3)2(4-Mepy)] (PPh3 = triphenylphosphine, 4-Mepy = 4-methylpyridine), a highly blue-luminescent mononuclear copper(i) complex, shows reversible emission colour change ranging from blue-green to red by vapour exposure to N-heteroaromatics, such as pyridine, pyrimidine, and 2-methylpyrazine. The remarkable colour changes occur due the ligand exchange reaction between the solid and gas. Su...
متن کاملSynthesis of Carbon Nanotubes on Cerium-Substituted Barium Ferrite Substrate by Chemical Vapor Deposition for Preparation of a Microwave Absorbing Nanocomposite
In this research, at first, Ce-substituted barium ferrite, BaCe0.2Fe11.8O19 was prepared via the sol-gel method as a substrate and then Carbon NanoTubes (CNTs) was synthesized on the surface of the substrate by Chemical Vapor Deposition (CVD) technique. The structure, morphology, and electromagnetic performance of the synthesized nanocompos...
متن کاملInvestigation of Barium Sulfate Precipitation and Prevention Using Different Scale Inhibitors under Reservoir Conditions
In this work, scaling tendency and amount of precipitation of barium sulfate (BaSO4) were determined; the process is depending on temperature, pressure and mixing ratio of injection and formation of waters. Results showed that BaSO4 precipitation is largely dependent on mixing ratio. Temperature and pressure had no influence on BaSO4 precipitation. Different sca...
