preparing these complexes which may find utility in molecular wire and metal–metal bond chemistries. The complexes reported herein have been characterised by X-ray diffraction, NMR, IR, UV/Vis, and Mössbauer spectroscopies, cyclic voltammetry, density functional theory calculations, and elemental analyses, which have enabled us to elucidate the electronic structure of the complexes and probe the variation

Protonation of CpFeH(P-P) (P-P = dppe, dppp) with HBF4 produced the molecular dihydrogen complexes [CpFe(H-2)(P-P)]BF4. Protonation of CpOsH(P-P) (P-P = dppm, dppe, dppp) with HBF4 at -78 degrees C gave a mixture of cis-[CpOsH(2)(P-P)]BF4 and trans-[CpOsH(2)(P-P)]BF4. Depending on the size of the chelating rings, the thermodynamically stable structures of the protonated products at room temperature may be exclusively trans-[CpOsH(2)(P-P)]BF4 or a mixture of cis-[CpOsH(2)(P-P)]BF4 and trans-[CpOsH(2)(P-P)]BF4. At room temperature in dichloromethane solutions, [CpOsH(2)(dppm)]BF4 exists as a mixture of cis and trans isomers in a ratio of 10:1, [CpOsH(2)(dppe)]BF4 exists as a mixture of cis and trans isomers in a ratio of 1:70, and [CpOsH(2)(dppp)]BF4 adopts only trans geometry.
