Au. Harkonen et al., SYNTHESIS, CRYSTAL-STRUCTURE AND CHARACTERIZATION OF THE HETEROMETALLIC TETRANUCLEAR BUTTERFLY CLUSTER [RU3IRH2(CO)(12)CL], Journal of organometallic chemistry, 519(1-2), 1996, pp. 205-208
A new iridium-ruthenium mixed-metal cluster [Ru3IrH2(CO)(12)Cl] has be
en synthesized and its structure has been determined by single-crystal
X-ray diffraction. [Ru3IrH2(CO)(12)Cl] shows a butterfly arrangement
of metal atoms; with three terminal carbonyls on each metal atom and w
ith the hydride ligands at Ru-Ru edges.
