Schematic representation of complex ions in the structures of (a) Tl(HPydc) (WARYEU; Rafizadeh et al., 2005), (b) [Bi(Pydc)Cl(H2O)] (MIPLUS; Ranjbar et al., 2001) and (c) [Ho(Pydc)(HPydc)] (QUPSUP; Fernandes et al., 2001). The right column represents pyridine-2,6-dicarboxylate ions with µ3 coordination (in accordance with IUPAC rules) as full circles. |
