Abstract
The complex cis-[Ru(bpy)(2)(PMe(o-tol)(2)Cl+] [ClO4-] crystallizes in space group P2(1)/c with a = 9.375(2) Angstrom, b = 22.019(7) Angstrom, c = 16.1 53(4) Angstrom, beta = 90.83(2)degrees, V = 3333.9(16) Angstrom(3) and D(ca lc'd) = 1.547 g/cm(3) for Z = 4. The Ru-PMe(o-tol)(2) bond length of 2.357( 3) Angstrom is significantly longer than distances of Ru-PMe2(o-tol) = 2.32 4(2) Angstrom and Ru-PMe3 2.310(2) Angstrom in analogous complexes. The cor responding Ru-P(o-tol)3 complex has eluded synthesis, probably due to steri c hindrance.
