The crystal structure of dimeric μ‐oxalato‐bis[(η 6 ‐ p ‐cymene)(triphenylphosphine)ruthenium(II)] bis(tetrafluoroborate), [Ru 2 (C 2 O 4 )(C 10 H 14 ) 2 (C 18 H 15 P) 2 ](BF 4 ) 2 , has the cation lying on an inversion centre. The complex demonstrates the trans bond‐weakening influence, with the longest Ru—C(η 6 ‐ p ‐cymene) bonds in the complex lying trans to the phosphine group. The related mononuclear species (η 6 ‐ p ‐cymene)(oxalato)(pyridine‐3,5‐dicarboxylic acid)ruthenium(II), [Ru(C 2 O 4 )(C 10 H 14 )(C 7 H 5 NO 4 )], crystallizes as hydrogen‐bonded tapes linked through O—H⋯O hydrogen bonds.
