A new diazine tetratopic helicand, H4L, is obtained from 3-formylsalicylic acid and hydrazine. The reaction between H4L and cobalt( II) perchlorate, iron(III) perchlorate, and sodium carbonate leads to triple-stranded tetranuclear anionic helicates, [(L3Co2Fe2III)-Fe-II](2-), which are connected through Na ions, resulting in chiral coordination polymers, [(infinity L3Na2Fe2Co2)-L-1(H2O)(4)(EtOH)(2)]center dot 3H(2)O.
