Complexes containing a Ru 2 n + 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 Ru 2 6+ -based complex, (H 2 pip) 2 [Ru 2 (hedp) 2 Cl 2 ]·6H 2 O (pip = piperazine) ( 1 ), isolated by...
