|Abstract:||A ruthenium(II) ethylene complex, <i style="">trans</i>-[Ru(H)(C<sub>2</sub>H<sub>4</sub>)-(dppm)<sub>2</sub>][BF<sub>4</sub>], bearing two 1,1-bis(diphenylphosphino) methane (dppm) ligands has been synthesized and structurally characterized using X-ray crystallography. In the molecular structure, the Ru<sup>II </sup>center shows a distorted octahedral coordination geometry formed by four P atoms of the two chelating dppm ligands, a hydride, and an ethylene ligands. The four dppm P atoms are almost co-planar with the hydride and the ethylene ligands perpendicular to this plane. The C-C bond distance of the bound ethylene is 1.375(6) Å, which is elongated by 0.042 Å as compared to free ethylene (1.333(2) Å). The packing diagram of the complex shows two voids or channels, which are occupied by BF<sub>4</sub><sup>–</sup> counterion and water molecules.|
