Bis(2,2'-bipyridine)(pyridine-2-carboxylate)ruthenium(II) hexafluorophosphate at 173K

K. Lashgari, R. Norrestam and B. Åkermark

Synopsis: The structure of the title compound, bis(2,2^'-bipyridine-N,N^')(pyridine-2-carboxylate-N,O)ruthenium( II) hexafluorophosphate, determined at 173K, is in good agreement with the structure determined at 295K [Canty et al. (1997). Inorg. Chim. Acta, 255, 117-123]. The coordination formed by five N atoms and one O atom around the Ru^II ion deviates substantially from octahedral symmetry. The relatively large thermal parameters of the F atoms in the PF₆ anion can be assumed as being due to substantial rigid group vibrations.
