Copper(I) π-coordination compounds with allyl derivatives of disubstituted pseudothiohydantoin: synthesis, structure investigation and nonlinear optical features

Cu(I) Arylsulfonate π-Complexes with 3-Allyl-2-thiohydantoin: The Role of the Weak Interactions in Structural Organization

“…9,10 Moreover, previously, we have shown, that Cu(I) π-complexes with allyl derivatives of heterocycles can possess noticeable non-linear optical properties. [11][12][13][14][15] This work is the continuation of our previous studies, in which we have studied the coordination behavior of 3-allyl-2-thiohydantoin (Hath) regarding Ag(I), where obtained coordination compounds have already shown interesting structural peculiarities, confirming the status of 2-thiohydantoin-based molecules as the potential ligands in the structural engineering. 16,17…”

Electrochemical Thin Film Deposition of Copper(I) Halides in Aqueous Solution: Substrate Extension and Structure Transformation

“…[19] In the standard state, disproportionation reaction of Cu(I) in aqueous solution is thermodynamically spontaneous. Thus, for Cu(I) halide based crystals, the previous synthetic methods (e.g., solution diffusion method, [20] solvothermal method, [21] and electrochemical synthesis method [22] ) need to keep water-free and oxygen-free environment to ensure the stability of Cu(I), especially for Cu(I) based bromides and chlorides. The reason is that the soft acid Cu(I) cannot be stabilized in aqueous solution by relatively hard base ligands Cl − and Br − .…”

Crystal structure and enantiomeric layer disorder of a copper(I) nitrate π-coordination compound

“…The interest in copper(I) -coordination compounds has risen over the last century since the first studies on ethylene absorption with copper(I) chloride solution (Berthelot, 1901;Manchot & Brandt, 1909). At present, the olefin Cu Icompounds are found to be important in biochemistry (Rodríguez et al, 1999;Abeles et al, 1994), as catalysts in organic syntheses (Perez & Diaz-Requejo, 2007;Dias et al, 2002;Straub et al, 1999;Li et al, 1995;Brandt et al, 2000), for their nonlinear optics activity (Fedorchuk et al, 2019;Hordiichuk et al, 2019;Slyvka et al, 2018a) and other useful properties (Zhang et al, 2002;Rickerby & Steinke, 2002;Park et al, 2006;Ye et al, 2007;Bellott & Girolami, 2009;Wang et al, 2005). In the last decade, special attention has been paid to the synthesis and investigation of copper(I) -compounds with allyl derivatives of heterocyclic organic compounds, since it has been found that the combination of the flexible allyl group and heterocyclic core played an important role in the stabilization of unique inorganic fragments of extremely rare or unknown in free state Cu I salts (Slyvka et al, 2013(Slyvka et al, , 2015Wang et al, 2015;Goreshnik & Mys'kiv, 2008;Goreshnik et al, 2011Goreshnik et al, , 2012.…”
