Bis(acetonitrile-N)(o-benzoquinone diimine-N,N ')-trans-bis(triphenylphosphine-P)ruthenium(II) bis(hexafluorophosphate) methanol solvate

The title complex, [Ru(C2H3N)(2)(C6H6N2)(C18H15P)(2)](PF6)(2). CH4O, is the third of a series of ruthenium complexes containing two triphenylphosphine groups in a trans arrangement, o-benzoquinone diimine and two other non-re dox active ligands to been characterized. The effect of electron donor-acce ptor properties of the two non-redox active ligands does not change the qui none arrangement for the o-benzoquinone diimine ligand, as can be seen from the bond distances of the quinone ring. The asymmetric unit contains half a molecule of complex cation (on a twofold rotation axis), one hexafluoroph osphate anion and half a molecule of methanol in a general position close t o a twofold rotation axis.
