Abstract

Complexes containing a Ru2n+ core (n = 4, 5 or 6) have been of great interest because of their variety of electronic configurations and magnetic properties. Herein, we report a novel homovalent Ru26+-based complex, (H2pip)2[Ru2(hedp)2Cl2]·6H2O (pip = piperazine) (1), isolated by the direct reaction of the mixed-valent Ru25+-based anion Ru2(hedp)23− [hedp = 1-hydroxyethylidenediphosphonate, CH3C(OH)(PO3)2] with oxidant peracetic acid under room temperature conditions. Magnetic measurements unambiguously confirm that this complex contains four unpaired electrons with a spin ground state of S = 2.
