Passing norbornadiene in Ar over a solution of RuCl24 in CH2Cl2 results in slow deposition of single crystals of theextremely insoluble title compound.The compound crystallizes in monoclinic space group P21/c with unit cell constants a 14.213(3), b 14.486(2), c 17.079(2) Angstroem, β 97.13(1)o, and ρc 1.50 g cm-3 for Z=4.Full-matrix least-squares refinement has led to a final R1 value of 0.057 based on 2460 independent observed (I 3?(I)) reflections.The molecule attains an approximately octahedral geometry with cis-chlorine and trans-phosphine ligands.The norbornadiene ligand bonds symmetrically to the metal with long C=C bonds of 1.408(12) and 1.415(12) Angstroem.The average values of some other important bond distances are: Ru-Cl 2.440 +/- 0.006 Angstroem; Ru-P 2.479 +/- 0.003 Angstroem; Ru-C 2.21 +/- 0.02 Angstroem.
