title: A novel nanosized {Co16} metallamacrocycle incorporating four linear {Co4} subunits bridged by polytriazolate ligands.
abstract: The solvothermal reactions of Co(II) salts and three rigid polytriazolate ligands lead to a linear Co(4) cluster, [Co(4)(3,5-bptp)(2)(OMe)(2)(NO(3))(2)(MeOH)(2)]·1.5H(2)O·MeCN (1), and a square-shaped {Co(16)} metallamacrocycle, [Co(16)(1,3-bptb)(4)(3,5-bptpt)(4)(OMe)(12)(H(2)O)(2)]·25H(2)O (2), which comprises four linear {Co(4)} subunits similar to those of 1 bridged by the longer 3,5-bptpt(3-) ligands into a nanoscale molecular square.
