| Abstract: | A new oxamato-bridged NiIICuIINiII 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 NiIICuIINiII 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. |
