In 2019,Journal of Molecular Structure included an article by Hajlaoui, Fadhel; Hadj Sadok, Ines Ben; Aeshah, H. Alamri; Audebrand, Nathalie; Roisnel, Thierry; Zouari, Nabil. HPLC of Formula: 7789-45-9. The article was titled 《Synthesis, crystal structures, second harmonic generation response and temperature phase transitions of two noncentrosymmetric Cu(II)-hybrid halides compounds: [(R)-C7H16N2][CuX4] (X = Cl or Br)》. The information in the text is summarized as follows:
(R)-(+)-3-aminoquinuclidine was used in the synthesis of [(R)-C7H16N2][CuCl4] (1) and [(R)-C7H16N2][CuBr4] (2), which both contain similar [CuX4]2- anions (X = Cl or Br). The structures of the two compounds were determined using single-crystal x-ray diffraction. The use of enantiomerically pure sources of (R)-C7H14N2 forces crystallog. noncentrosymmetry. These materials crystallize in the chiral space group P212121, which exhibits the enantiomorphic crystal class 222 (D2). In the mol. arrangement, the [CuX4]2- anions are linked to the organic cations through N-H···X and C-H···X H bonds to form cation-anion-cation mol. units, which are held together by offset face-to-face interactions giving a three-dimensional network. Thermal stability of the crystals was ascertained by TG measurement. 1 And 2 display several phases transition with higher transition temperature at T = 100°. The Kurtz and Perry powder method using Nd:YAG laser shows that their 2nd harmonic generation (SHG) efficiencies are ∼0.81 and 0.82 times as large as that of KH2PO4 (KDP), resp. Such a chiral hybrid metal halides skeleton could provide a new platform for future engineering in the areas including information storage, light modulators and optoelectronic functionalities. After reading the article, we found that the author used Cupric bromide(cas: 7789-45-9HPLC of Formula: 7789-45-9)
