The solvothermal reactions of CoII salts and three rigid polytriazolate ligands lead to a linear Co4 cluster, [Co4(3,5-bptp)2(OMe)2(NO3)2(MeOH)2]·1.5H2O·MeCN (1), and a square-shaped Co16} metallamacrocycle, [Co16(1,3-bptb)4(3,5-bptpt)4(OMe)12(H2O)2]·25H2O (2), which comprises four linear Co4} subunits similar to those of 1 bridged by the longer 3,5-bptpt3− ligands into a nanoscale molecular square.
