large cone angles give only the anti isomer. Disubstituted complexes [Re2(μ-H)(μ-Snaph)(CO)6L2] [L = NCMe (3a), pyridine (3b), PPh3 (3c)] and [Re2(μ-H)(μ-Snaph)(CO)6(μ-L–L)] [L–L = dppm (4a), dppe (4b)] were prepared in a similar way. The reaction of [Re2(μ-H)(μ-SH)(CO)8] 5 with one equivalent of tmno and PPh3 gave [Re2(μ-H)(μ-SH)(CO)6(PPh3)2] 6 in 38% yield. Compound 6 is rigid on the timescale of 31P
p-BrC6H4) with Ru3(CO)12 yielded clusters of the type [(μ2-H)2Ru3(CO)9(μ3-PR)] and [Ru3-(CO)9(μ3-PR)2]. The reaction of C6H5AsH2 with Ru3(CO)12 gave [(μ2-H)2Ru3-(CO)9(μ3-AsC6H5)] and [Ru2(CO)6(μ2-As(C6H5)H)2]. All the compounds have been studied by IR and NMR (31P and 1H) spectroscopy and the structure of [(μ2-H)2Ru3(CO)9(μ3-P(p-CH3OC6H4))] has been determined by single crystal X-ray diffraction (R

A composition comprising the following structure: (1) wherein Re represents a rhenium ion having a +1 charge; (I) represents an uncharged bidentate ligand containing at least one ring containing a ring nitrogen atom bound to the rhenium (Re), and the bidentate ligand containing another nitrogen atom, either in a ring or not in a ring, bound to the rhenium (Re); and L1, L2, L3, and L4 are neutral ligands with at least one neutral ligand being an isonitrile ligand of the formula -CN-R, wherein R is an aliphatic or aromatic hydrocarbon group containing 1-20 carbon atoms; and X- represents a non-coordinating monovalent anion; wherein the bidentate ligand and R are optionally substituted by one or more groups selected from (i)-(xi) as further discussed above. Methods for treating a condition that benefits from ER stress induction, such as cancer, by administering the above rhenium complex are also disclosed.
