Description

Crystal adducts of acid oxysalts with hydrogen fluoride, i.e. CsH2PO3·HF (1) and Cs4(SeO4)(HSeO4)2·HF (2) were synthesized. By the method of X-ray diffraction analysis of monocrystals at 180 K crystal structure of compounds 1 and 2 was determined respectively: 1 - a = 5.581 (2), b = 4.863 (2), c = 18.400 (7) A, β = 92.09 (3) deg, sp.gr. P21/c; 2 - a = 25.413 (5), b = 12.718 (3), c = 10.819 (2) A, β 107.57 (3) deg, sp.gr. C2/c. Besides hydrogen bonds of used type O-H-O shorter bonds F-H-O, their length 2.36-2.44 A, were discovered in the structures studied

Abstract (Russian)

Синтезированы кристаллические аддукты кислых оксосолей с фтористым водородом CsH2PO3·HF (1) и Cs4(SeO4)(HSeO4)2·HF (2). Методом рентгеноструктурного анализа монокристаллов при 180 К определено кристаллическое строение соединений 1 и 2 соответственно: 1 - a = 5.581 (2), b = 4.863 (2), c = 18.400 (7) A, β = 92.09 (3) град, пр.гр. P21/c; 2 - a = 25.413 (5), b = 12.718 (3), c = 10.819 (2) A, β = 107.57 (3) град, пр.гр. C2/c. В изученных структурах помимо водородных связей обычного типа О-Н-О обнаружены более короткие связи F-H-O длиной 2,36-2,44 А
