摘要

A new oxamato-bridged (NiCuNiII)-Cu-II-Ni-II species, [Ni(iprtacn)](2)[Cu(pba)(H2O)(0.5)](BPh4)(2) (1), (iprtacn = 1,4,7-triisopropyl-1,4,7-triazacyclononane; pba = 1,3-propylenebis(oxamato)) has been synthesized and structurally as well as magnetically characterized. Complex 1 has a discrete trinuclear (NiCuNiII)-Cu-II-Ni-II structure: Two nickel(II) ions are bridged by [Cu(pba)](2-) with the macrocyclic ligand iprtacn a terminal ligand of nickel(II). Fitting the magnetic data of 1 led to g(Cu) = 2.16, g(Ni) = 2.18, J = -112.5 cm(-1), D = 7.78 cm(-1). The irregular spin state structure and interaction of complex 1with DNA are described here.
