• Two new ruthenium(II) complexes of formula [Ru(bpy)2(L1)][PF6] and [Ru(bpy)2(L2)][PF6]2 are reported. HL1 is a (nitrophenyl)ethenyl‐substituted phenylpyridine ligand, and L2 is the bipyridine analogue of HL1. The X‐ray crystal structure of [Ru(bpy)2(L1)][PF6] has been solved, and the compound is found to crystallize in the monoclinic C2/c space group. The electronic spectrum of the cyclometalated derivative [Ru(bpy)2(L1)][PF6] exhibits a low‐lying transition that is red‐shifted from 454 to 546 nm relative to that of the parent bipyridine‐based complex, which reveals an important charge‐transfer character. To support this assumption, the nonlinear optical properties were investigated by the hyper‐Rayleigh scattering technique and indicate a molecular static hyperpolarizability (β0) equal to 230 × 10–30 cm5 esu–1.
