Crystal structure of cis-[Rh(biq)2Cl2]Cl·3H2O: Solid-state characterization and crystal packing analysis

3-Ammoniopyridinium tetrabromidomercurate(II) monohydrate

“…[2.6309 (7) and 2.6216 (7) Å, respectively]. These lengths fall within the range of Hg-Br distances reported previously for compounds containing [HgBr 4 ] 2anions (Al-Far et al, 2006;. It is noteworthy that the longer Hg-Br2, Br3 bonds are involved in more interactions than the shorter ones (Table 2).…”

“…CommentNoncovalent interactions play an important role in organizing structural units in both natural and artificial systems(Desiraju, 1997). In connection with ongoing studies(Al-Far et al, 2006; Al-Far & Ali 2007a,b; Ali & Al-Far 2007a,b;…”

“…For general background, see: ; Desiraju (1997). For related literature, see: Al-Far, Ali & Al-Sou'od (2006); ; ; Ali, Al-Far & Haddad (2008). For bond distances see: Orpen et al (1989).…”

2,5-Dibromopyridinium hexabromidostannate(IV)

“…Non-covalent interactions play an important role in organizing structural units in both natural and artificial systems (Desiraju, 1997). In connection with ongoing studies (Willett et al, 2000;Luque et al, 2001;Haddad & Al-Far, 2003;Al-Far et al, 2006;Ali et al, 2007; of the structural aspects of pyridinium salts of bromo-metal anions, we report the crystal structure of the title compound, (I).…”
