“…It is also worthy of note that Os-P distances are slightly longer in 2 and 3, than in the simple substituted phosphine complex [Os 3 (CO) 11 (PR 3 )] [23]. The same trend is observed when the Os-P distance of the g 1 -dppm ligand in [Os 3 (-CO) 9 (l-dppm)(g 1 -dppm)] is compared with the corresponding value in 5 [24]. This lengthening could be the result of the steric effect induced by the alkyne coordination.…”

“…Two 12-MC Ru -3 complexes have been synthesized with no μ 3 -guest but with the guest binding terminally to each ring Ru. In one structure each Ru is bound by two chloride anions and one bis(dimethylphosphino)methane ligand that binds bidentate to form a four-membered chelate ring (Figure ), and in the second structure each Ru center is bound to two CO groups. ,

“…The reaction of bidentate phosphines with the activated triosmium clusters Os 3 (CO) 12 - n (MeCN) n ( n = 1, 2) and Os 3 (CO) 10 L 2 (L 2 = 1,5-cod, 1,3-butadiene) has been investigated over the years with respect to the bonding mode adopted by the bidentate P ligand upon coordination. Simple coordination of diphosphine ligands at these activated clusters typically proceeds to furnish a bridged or chelated cluster Os 3 (CO) 10 (P−P), where the P−P ligand is bound to adjacent osmium centers or attached to a single osmium atom: While several unequivocal examples exist for the isomerization of a diphosphine ligand at other polynuclear clusters, , no such studies have been reported for the family of Os 3 (CO) 10 (P−P) clusters. The resulting Os 3 (CO) 10 (P−P) clusters have been shown to exhibit some interesting chemistry, due to phosphine-assisted stabilization of cluster unsaturation.…”
