Preparation of antimony(V) trichloride difluoride and its characterization by means of X-ray crystallography, antimony-121 Mössbauer, and Raman spectroscopy

Synthesis conditions and activity of various Lewis acids for the fluorination of trichloromethoxy-benzene by HF in liquid phase

“…The activities of Lewis acids with an oxidation state of +Vare mainly related to their abilities to form mixed halides, very reactive nucleophilic species, with HF as reported in the literature [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. The difference of activities could also correspond to their solubilities in the organic reactional medium.…”

KBa3M2F14Cl (M = Zr, Hf): novel short-wavelength mixed metal halides with the largest second-harmonic generation responses contributed by mixed functional moieties

“…The bond valence sum (BVS) results for K + , Ba 2+ , Zr 4+ /Hf 4+ , F − , and Cl − ions are 0.97, 2.13-2.23, 4.00, 0.93-1.09, and 1.06 for KBZFC, and 0.98, 2.11-2.25, 4.12, 0.82-0.97, 1.08 for KBHFC, respectively (Table S2 †). 57 Related information for NCS halides with mixed uorine and chlorine atoms are summarized in Table S4, † and six of them belong to the tetrahedral system (I4: SbCl 3 F 2 , 58 − units, and Cl/Br atoms ll in the middle of the rings. 55,64 Nevertheless, the MF 7 units in KBZFC and KBHFC form the 0D structure that compensates for large anisotropy.…”

“…Related information for NCS halides with mixed fluorine and chlorine atoms are summarized in Table S4, † and six of them belong to the tetrahedral system ( I 4: SbCl 3 F 2 , 58 SbF 1.6 Cl 3.4 , 59 I 4̄:TaCl 4 F, 60 SbCl 4 F, 61 SbCl 3 F 2 , 62 and I 4̄2 m : CsSbF 3 Cl 63 ). They show similar 0D structures, and a representative of the group, CsSbF 3 Cl, is composed of four fundamental building units, the [SbF 3 Cl 2 ] anionic group, which is interconnected by shared F atoms that form isolated [Sb 4 F 12 Cl 4 ] units.…”

MX 5-Ketten aus eckenverknüpften oktaedern. Mögliche Kettenkonfigurationen und mögliche Kristallstrukturen beidichtester Packung der X-Atome

“…Die Fluoridchloride NbCI4F (Preiss, 1968), TaChF (Preiss, 1966a), SbC14F (Preiss, 1966b), SbC14 ~F,., (Ballard, Birchall & Slim, 1979;Miiller, 1979b) und SbCI3F2 (Ballard, Birchall & Slim, 1977) bilden z4-Ringe, besitzen aber ebenfalls keine dichteste Anordnung der Halogenatome, m/Sglicherweise wegen der unterschiedlichen GrSJ3e von F-und C1-Atomen.…”
