H. Wadepohl et al., Synthesis and X-ray structure of a cluster complex with facial coordination of cyclooctatetraene to a Co2Ni triangle, CHEM COMMUN, (4), 1999, pp. 389-390
The reaction between [(eta-C5H5)NiCo3(CO)(9)] and cyclooctatetraene yields
[Co2Ni(CO)(6)(mu(3)-eta(2) : eta(3) : eta(3)-C8H8)] with a cyclooctatetraen
e ligand in the facial coordination mode to a heterometallic Co2Ni triangle
