Bis(2-bromopyridinium) hexabromidostannate(IV)

“…The (SnBr 6 ) 2anion forms a quasi-octahedral geometry (Table 1), with the Sn-Br bond lengths are almost invariant. These lengths are in accordance with tin-bromide distances reported for (SnBr 6 ) 2anion containing compounds (Willey et al,1998;Tudela & Khan 1991;Ali, Al-Far & Al-Sou'od, 2007;Ali, Al-Far & Ng, 2007). Bond lengths and angles within the cation are as expected (Allen et al, 1987).…”

“…Within our research of hybrid compounds containing tin metal Ali, Al-Far & Al-Sou'od, 2007;Ali, Al-Far & Ng, 2007), the crystal structure of the title salt, (I), has been investigated.…”

“…The title salt is isomorphous with the Te analogue (Fernandes et al, 2004). For related literature, see: ; Ali, Al-Far & Al-Sou'od (2007); ; Ali, Al-Far & Ng (2007); Allen et al (1987); Aruta et al (2005); Hill (1998); Kagan et al (1999); Knutson et al (2005); Raptopoulou et al (2002); Tudela & Khan (1991); Willey et al (1998).…”

“…Our strategy is to use aromatic compounds to encourage aryl•••aryl packing arrangements of various types, using substituted pyridinium in order to facilitates associations, and halo salts that can involve in X•••X interactions as well as X•••aryl and X•••H interactions. Within our research of hybrid compounds containing tin metal (Al-Far & Ali 2007;Ali, Al-Far & Al-Sou'od, 2007;Ali, Al-Far & Ng, 2007), the crystal structure of the title salt, (I), has been investigated.…”
