TEXT _publ_section_abstract ; The structures of aminotriphenylphosphonium bromide and hexachloroantimonate are stabilized by hydrogen bonds. ; _publ_section_comment ; The aminotriphenylphosphonium bromide (I) and hexachloroantimonate (II) have been structurally characterized. There are two formula units of (II) in the asymmetric unit. Both compounds form hydrogen bonds from the amino hydrogen atoms to the anions. The positions of the amino hydrogen atoms were refined with distance restraints for the N-H distances. The N-Br distances in I are 3.310(2) and 3.373 (2) \%A, the N-Cl distances in II are 3.594 (4), 3.563(4), 3.740(5) and 3.537(5) \%A. All other distances and angles are generally as expected. They correspond well with values found in the aminotriphenylphosphonium chloride (Hursthouse, Walker, Warrens @ Woolins, 1985), the aminotriphenylphosphonium (1,2,-bis(benzamid-2'-olato)phenyl- N,N',O,O')nitrido osmium (IV) (Barner, Collins, Maper and Santasiero, 1986) and the amino triphenylphosphonium (di(thiazane)-3-eno-N,S)-thiosulfato- triphenyl-phosphine platinum (Hursthouse, Short, Kelly @ Woolins, 1988). ; _publ_section_experimental ; Data were collected by the real-time learnt profile method (Clegg, 1981). Scattering factors, dispersion corrections and absorption coefficients were taken from International Tables for Crystallography, Vol. C. (1992), tables 6.1.1.4, 4.2.6.8 and 4.2.4.2 respectively. Since I crystallizes in a polar space group, polar axis restraints were applied by the method of Flack @ Schwarzenbach (1988) and the absolute structure of the crystal used for the investigation was established as described by Flack (1983). ; _publ_section_references ; Barner, J.C., Collins, T.J., Mapes, B.E. @ Santasiero, B.D.
