A new RuII–ReII complex salt, -cyanido- 2C:N-bis[( 5-cyclopentadienyl)bis-
(3,5,7-triazaphosphaadamantane- P)ruthenium(II)] tetrabromido(ethanol/
methanol- O)nitrosylrhenate(II), [Ru(CN)(C5H5)2(C6H12N3P)4][ReBr4(NO)-
(CH4O)0.5(C2H6O)0.5] or [RuCp(PTA)2– -CN–1 C:2 2N-RuCp(PTA)2]-
[Re(NO)Br4(EtOH)0.5(MeOH)0.5] (PTA = 3,5,7-triazaphosphaadamantane)
was obtained and characterized by single-crystal X-ray diffraction, elemental
analysis and infrared spectroscopy. The title salt was obtained by liquid–liquid
diffusion of methanol/DMSO solutions of (NBu4)[Re(NO)Br4(EtOH)] and
[(PTA)2CpRu– -CN–1 C:2 2N-RuCp(PTA)2](CF3SO3). The RuII and ReII
independent moieties correspond to a binuclear and mononuclear complex
ion, respectively. A deep geometrical parameter analysis was performed, and no
significant differences were found with earlier reports containing similar
molecules. The magnetic properties were investigated in the temperature range
2.0–300 K, and the complex behaves as a qua...
