In 2005,Robertson, Daniel; Cannon, John F.; Gerasimchuk, Nikolay published 《Double-Stranded Metal-Organic Networks for One-Dimensional Mixed Valence Coordination Polymers》.Inorganic Chemistry published the findings.Product Details of 31938-07-5 The information in the text is summarized as follows:
The design of new types of metal-organic networks and the search for unusual crystal architecture represents an important task for modern inorganic and materials chem. research. A group of new monosubstituted phenylcyanoximes, containing F, Cl, and Br atoms at the 2, 3, or 4 positions, were synthesized using the high yield nitrosation reaction with CH3-ONO and were spectroscopically (1H NMR, 13C NMR, UV-visible, IR, mass spectrometry) and structurally characterized. Results of x-ray anal. revealed nonplanar trans-anti geometry for 2-chlorophenyl(oximino)acetonitrile, H(2Cl-PhCO); a nonplanar anti configuration for 4-chlorophenyl(oximino)acetonitrile, H(4Cl-PhCO); and planar cis-syn geometry for 3-fluorophenyl(oximino)acetonitrile, H(3F-PhCO). All arylcyanoximes undergo deprotonation in solutions with the formation of colored anions exhibiting pronounced neg. solvatochromism in polar protic and aprotic solvents. Nine Tl(I) cyanoximates were obtained using the reaction between hot (∼95°) aqueous solutions of Tl2CO3 and solid powdery monohalogenated arylcyanoximes HL. Crystal structures of two Tl(I) cyanoximates [Tl(2Cl-PhCO) and Tl(4Br-PhCO)] contained centrosym. dimeric units (TlL)2 that are connected to a coordination polymer by an O atom of the oxime group of the neighboring mol. Cyanoxime anions act as bridging ligands in both structures where the polymeric motif consists of double-stranded Tl-O chains interconnected with the formation of zigzagging Tl2O2 planar rhombes. Tl atoms form infinite linear arrays with close intermetallic separations The nearest Tl(I)···Tl(I) distances are 3.838 and 4.058 Å in the Tl(2Cl-PhCO) and Tl(4Br-PhCO) structures, resp., close to that in metallic Tl (3.456 Å). Monosubstituted Ph groups are well aligned in π-stacking columns that are perpendicular to the array of Tl(I) atoms and stabilize formed structures. Coordination polyhedrons of Tl(I) in these complexes represent distorted trigonal pyramids with stereoactive lone pair. After reading the article, we found that the author used 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5Product Details of 31938-07-5)
2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5) has been used in the synthesis of 2-(1-cyano-1-(3-bromophenyl))methylidene-3-phenylthiazolidine-4,5-dione or a series of aminoethylbiphenyls, novel 5-HT7 receptor ligands.Product Details of 31938-07-5
