Abstract In continuation of the study focused on synthesis and structure mimics active site [FeFe] hydrogenase enzyme, reaction Fe 3 (CO) 12 with cyclopropyl ferrocenyl thioketone 1 was carried out. Two different complexes ring‐opened fragments were isolated identified as η 4 ‐1‐thia‐1,3‐diene‐type mononuclear tricarbonyl iron complex 2 ‐acyl‐type hexacarbonyl diiron , respectively. Structures ...

Highly efficient photoswitching tetranuclear rhenium(I) tricarbonyl diimine complexes with a stilbene-like bridging ligand are reported. The ability to directly populate excited states localized on the bridging ligand is the key for the observed efficient photoisomerization.

Ultrafast two-dimensional infrared (2D IR) vibrational echo spectroscopy has proven broadly useful for studying molecular dynamics in solutions. Here, we extend the technique to probing the interfacial dynamics and structure of a silica surface-tethered transition metal carbonyl complex--tricarbonyl (1,10-phenanthroline)rhenium chloride--of interest as a photoreduction catalyst. We interpret th...

The synthesis and full characterization of two tetrathiafulvalene-appended azine ligands, namely 2-([2,2'-bi(1,3-dithiolylidene)]-4-yl)-6-((2,4-dinitrophenyl)hydrazono)methyl)pyridine (L1) and 5-([2,2'-bi(1,3-dithiolylidene)]-4-yl)-2-((2,4-dinitrophenyl)hydrazono)methyl)pyridine (L2) are described. The crystal structure of ligand L1 indicates that the ligand is completely planar with the presen...

Molybdenum and tungsten complexes M(h-C5H4CH2-h-CH2)(CO)3 (M=Mo, W) containing the bidentate ethyl-functionalized cyclopentadienyl ligand C5H4CH2CH2 have been synthesized by the reaction of spiro[2.4]hepta-4,6-diene with M(CO)3L3 (M=Mo; L3=1,3,5-C6H3Me3; M=W; L=NCMe). Reaction of the more stable tungsten complex with C6H5ICl2 and HBF4 gave complexes of the type W(h-C5H4CH2CH2Cl)(CO)3Cl, W(h-C5H...

The title compound, [W(C(5)H(5))(HOBF(3))(CO)(3)], has a four-legged piano-stool geometry which is typically found for C(5)H(5)W(CO)(3)X complexes. The HOBF(3)(-) anion is the hydrolysis product of BF(4)(-) and is coordinated via oxygen.
