Tin–bromine bond lengths and mössbauer quadrupole splittings of tin(IV) bromide complexes. Crystal structure of pyridinium tetrabromodiphenylstannate(IV)

2,3-Dimethylquinoxalinediium hexabromidostannate(IV) trihydrate

“…The bond lengths and angles (Table 1) are generally within normal ranges (Allen et al, 1987). In the anion, the Sn1-Br1 [2.4406 (12) Å] and Sn1-Br3 [2.4605 (12) Å] bonds are shorter than the other Sn-Br bonds, in which they are within the range of Sn-Br bonds reported previously for compounds containing [SnBr 6 ] 2anions Al-Far & Ali, 2007a,b;Al-Far et al, 2007;Tudela & Khan, 1991;Willey et al, 1998). In the cation, the bond lengths and angles are in accordance with the corresponding values (Al-Far & Ali, 2007a,b;.…”

Bis(2-amino-3,5-dibromo-4,6-dimethylpyridinium) hexabromidostannate(IV)

“…The SnÐBr distances are in the range 2.5606 (6)± 2.6443 (6) A Ê for the Sn1 anion, with a mean value of 2.6001 (6) A Ê , and in the range 2.5699 (6)±2.6326 (6) A Ê for the Sn2 anion, with a mean value of 2.6013 (6) A Ê . These bond lengths fall within the range of SnÐBr distances reported previously for compounds containing [SnBr 6 ] 2À anions (Willey et al, 1998;Tudela & Khan, 1991).…”

2,5-Dibromopyridinium hexabromidostannate(IV)

“…The anion exhibits a distorted octahedral arrangement about atom Sn1, which lies on a crystallographic twofold rotation axis. The Sn1-Br1 bond is slightly longer than the Sn1-Br2 and Sn1-Br3 bonds, and these are comparable to corresponding bonds reported previously (Willey et al, 1998;Tudela & Khan 1991;Ali et al, 2007;. In the brominated cation, the bond lengths and angles are nearly the same as the corresponding geometry in similar compounds (Liu et al, 2001;Albrecht et al, 2003;Prince et al, 2003;Haddad et al, 2004).…”
