Immobilized rhenium tricarbonyl complexes were embedded in ALD deposited ZrO2, and investigated by (time resolved) infrared spectroscopy. The initially solvent exposed molecules react on the change of their environment.

The replacement of one pyrazole ligand by 2-aminopyridine in previously known rhenium tricarbonyl pyrazole complexes leads to more selective anion hosts.

Mn(I) carbonyl terpyridyl complexes have been synthesized and characterized. The tricarbonyl derivative exhibits interesting behaviors for controlled CO-release by both thermal and photosynthetic pathways.

Tricarbonyl hydride derivatives of cyclopentadienyl-chromium, -molybdenum and -tungsten compounds covalently linked to a macroreticular polystyrene support are obtained by treatment of polystyrene-attached cyclopentadienyl anions with the respective metal hexacarbonyl and subsequent acidification. In contrast to the ease with which unsupported cyclopentaruenyl·chromium and -molybdenum tricarbon...

In the title compound, [Re(C10H6NO2)(CO)3{As(C6H5)3}], the coordination environment of Re(I) is that of a distorted octa-hedron. Three coordination sites are occupied by three carbonyl groups in a facial arrangement and the remaining three sites by tri-phenyl-arsane and deprotonated quinaldic acid in As-mono- and N,O-bidentate fashions, respectively. In the crystal, the complexes are linked thr...

In the title molecule, C(9)H(3)Cl(3)O(3), there are three short interactions involving the benzene H atoms and the chloro-formyl Cl atoms. In the crystal, mol-ecules stack along the a axis with no significant non-bonded inter-actions.

130 years after Mond discovered the first homoleptic carbonyl complex Ni(CO)4, we report on a [Ni(CO)4].+ salt as synthesis of any nickel cation in condensed phase. It was prepared by oxidation metal with synergistic oxidant Ag[F{Al(ORF)3}2]/0.5 I2 (RF=C(CF3)3) CO atmosphere. This D2d-symmetric metalloradical represents last missing entry among structurally characterized cations Groups 6 to 11....

Rhenium(I) N-heterocyclic carbene (NHC) complexes of the type fac-[Re(CO)3(NHC)L] with either azide or triazolate ancillary ligands L and pyridyl or pyrimidyl substituted imidazolyl units have been prepared and structurally characterised, and their photophysical and photochemical properties studied. All of the complexes exhibit phosphorescent emission from triplet metal-to-ligand (MCLT) excited...
