Tomazela, Marcos N. Eberlin, and Henrique E. Toma, Inorganic Chemistry, 2004, 43 (11), pp 3521–7. DOI: 10.1021/ic0352250. (Thanks to Mark Dionne for bringing this to our attention.) The authors, at Universidade de São Paulo and Universidade Estadual de Campinas, Brazil, report [AIR 16:1]:

Two novel ruthenium polypyridine complexes, [Ru(bpy)2Cl(BPEB)] (PF6) and {[Ru(bpy)2Cl]2(BPEB)} (PF6)2 (BPEB = trans-1,4-bis[2-(4-pyridyl)ethenyl]benzene), were synthesized and their characterization carried out by means of elemental analysis, UV−visible spectroscopy, positive ion electrospray (ESI-MS), and tandem mass (ESI-MS/MS) spectrometry, as well as by NMR spectroscopy and cyclic voltammetry.
