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.

《Planochromism of cyanoxime anions: Computational and mechanistic studies in solid state and solutions》 was published in Inorganica Chimica Acta in 2020. These research results belong to Morton, Jeffrey; Dennison, Richard; Nemykin, Victor; Gerasimchuk, Nikolay. Application In Synthesis of 3-Oxo-3-phenylpropanenitrile The article mentions the following:

The benzoylcyanoxime, NC-C(=N-OH)-C(O)-C6H5 (later H(BCO)), represents a new ampolydentate ligand that received attention in the light of useful biol. properties of its coordination compounds Colorless H(BCO), upon deprotonation, gains color that depends on the counter-cation and the system in general. Five derivatives of H(BCO), with colorless organic and inorganic mono-cations – Cs, Tl, Ag, N(CH3)4 and As(C6H5)4 – were synthesized and characterized by the X-ray anal., vibrational and electronic spectroscopy. Compounds exhibited unexpected and significant differences in color, both in solid state and in solutions, that were challenging to explain, thereby warranting detailed investigation including high-level DFT/TDFT computations. It was found that the BCO- anion demonstrates neg. solvatochromic in polar protic ROH (R=H, CH3, C2H5, C3H7, C4H9) solvents, and appears yellow in color, as tetraalkylammonium or alkali metal salts. In polar aprotic solvents, such as CH3CN, DMF, and DMSO, solutions of the BCO- anion are red. The color originates from n → π * transition in the anion. Solid state structures evidenced a considerable dependence on planarity of the BCO- anion on its color, as well as on the character of bonding in the C-N-O fragment: yellow color is associated with an oxime (bond length C-N is shorter than N-O), while red color is due to the nitroso character (bond length C-N is longer than the N-O). An addition of ethanol to red solutions of the BCO-containing salts leads to the color change to yellow, which is the result of the formation of an H-bond between the C-N-O fragment of cyanoxime and the solvent, also leading to the flattening of the structure. An explanation for this new color-changing effect was offered, based on exptl. evidence and TD/DFT calculations In the experiment, the researchers used 3-Oxo-3-phenylpropanenitrile(cas: 614-16-4Application In Synthesis of 3-Oxo-3-phenylpropanenitrile)
