CRYSTAL-STRUCTURE OF THE METHANOL SOLVATE OF (ETA(5)-CYCLOPENTADIENYL) [1,2-BIS (DIPHENYLPHOSPHINO)ETHANE]NITRORUTHENIUM(II), RU(ETA(5)-C5H5)(DPPE)(NO2)CENTER-DOT-CH3OH
Mr. Churchill et al., CRYSTAL-STRUCTURE OF THE METHANOL SOLVATE OF (ETA(5)-CYCLOPENTADIENYL) [1,2-BIS (DIPHENYLPHOSPHINO)ETHANE]NITRORUTHENIUM(II), RU(ETA(5)-C5H5)(DPPE)(NO2)CENTER-DOT-CH3OH, Journal of chemical crystallography, 26(7), 1996, pp. 489-495
The title complex crystallizes in the centrosymmetric monoclinic space
group C2/c (No. 15) with Z = 8, The structure was refined to R = 4.49
% for those 2745 independent reflections with 2 theta = 5-50 degrees a
nd \F-sigma\ 6 sigma(F). Ruthenium-ligand distances are as follows: Ru
-P = 2.284(2) and 2.286(2) Angstrom, Ru-NO2 = 2.049(6) Angstrom and Ru
-C(Cp) 2.210(10)-2.246(9) Angstrom. Bond lengths within the nitro liga
nd are N(1)-O(1) = 1.226(10) Angstrom and N(1)-O(2) = 1.244(10) Angstr
om. The methanol of solvation is ordered but is subject to large therm
al vibrational motions.
