corresponding [M(η-arene)X(C5H5N)2] with HBF4 in methanol then provides a high yield of the triple halide-bridged complexes [M2(η-arene)2X3]BF4. Spectroscopic evidence for the formation of hetero-bridged, heteroarene and heteronuclear triple halide-bridged arene complexes of ruthenium(II) and osmium(II) using this synthethic route is also discussed.
