mer-trans-W(CO)3(PR3)2(η2-H2) Viewing tools To simplify: The structure shown is a compilation of a X-ray crystal structure determination and a neutron diffraction study. A difference map of the two superimposed data sets allowed the authors to locate the positions of the hydrogens in the H2 ligand. CCDC structure: CEJDEA Kubas, G.J., Ryan, R.R., Swanson, B.I., Vergamini, P.J., Wasserman, H.J.; J. Am. Chem. Soc., 106 1984, p. 451-452

Computational Energy Minimization for mer-trans-W(CO)3(PR3)2(η2-H2) Viewing tools To simplify: The optimization results in the structure where the H-H bond is parallel to the P-W-P bond axis suggested as likely by the authors on P 452
