摘要：
The complex cis-[Ru(bpy)2{PMe(o-tol)2}Cl+][ClO−4] crystallizes in space group P21/c witha = 9.375(2) Å, b = 22.019(7) Å, c = 16.153(4) Å, β = 90.83(2)°, V = 3333.9(16) Å3 and D(calc'd) = 1.547 g/cm3 for Z = 4. The Ru-PMe(o-tol)2 bond length of 2.357(3) Å is significantly longer than distances of Ru-PMe2(o-tol) = 2.324(2) Å and Ru-PMe3 = 2.310(2) Å in analogous complexes. The corresponding Ru-P(o-tol)3 complex has eluded synthesis, probably due to steric hindrance.
