Oxalate complexes of the (⁶-p-cymene)ruthenium(II) fragment: -oxalato-²O¹,O²:²O^1',O^2'-bis[(⁶-p-cymene)(triphenylphosphine-P)ruthenium(II)] bis(tetrafluoroborate) and (⁶-p-cymene)(oxalato-²O,O')(pyridine-3,5-dicarboxylic acid-N)ruthenium(II)

Abstract: The crystal structure of dimeric [mu] -oxalato-bis[( [eta] ⁶-p-cymene)(triphenylphosphine)ruthenium(II)] bis(tetrafluoroborate), [Ru₂(C₂O₄)(C₁₀H₁₄)₂(C₁₈H₁₅P)₂](BF₄)₂, has the cation lying on an inversion centre. The complex demonstrates the trans bond-weakening influence, with the longest Ru-C( [eta] ⁶-p-cymene) bonds in the complex lying trans to the phosphine group. The related mononuclear species ( [eta] ⁶-p-cymene)(oxalato)(pyridine-3,5-dicarboxylic acid)ruthenium(II), [Ru(C₂O₄)(C₁₀H₁₄)(C₇H₅NO₄)], crystallizes as hydrogen-bonded tapes linked through O-HO hydrogen bonds.

Formula: [Ru₂(C₂O₄)(C₁₀H₁₄)₂(C₁₈H₁₅P)₂](BF₄)₂ and [Ru(C₂O₄)(C₁₀H₁₄)(C₇H₅NO₄)]
