A nano-scale double-wheel-like framework: A novel assembly of six ferrocenedicarboxylate units with unusual coordination modes

Six ferrocenedicarboxylate units with unprecedented coordination modes assembled with four Pb(II) and four Na(I) simultaneously resulting in a novel nano-scale double-wheel- like framework [Pb4Na4(O2CFcCO2)6(H2O)6] · 6CH3OH · 2H2O, whose structure and electrochemical properties were characterized.
