Protonation of the CoRh bond in CoRh(μ-CO)(CO)2(μ-dppm)2

Journal of Molecular Structure: THEOCHEM, 1996
Abstract The electronic structure of CoRh(μ-CO)(CO) 2 (μ-H 2 PCH 2 PH 2 ) 2 and CoRh(μ-H)(μ-CO)(CO) 2 (μ-H 2 PCH 2 PH 2 ) 2 has been investigated by means of density functional calculations (DFT). The tetrahedral environment around the cobalt atom is the origin of the lack of direct metal-metal interaction in the former complex.

An octanuclear [Co(ii)2–Co(iii)2]2 interlocked grid—example of an inorganic [2]catenane

Chemical Communications, 2005
An oxalic dihydrazide based flexible polydentate amidrazone ligand undergoes spontaneous [2 x 2] grid assembly, followed by partial disassembly, and then reassembly in the presence of Co(NO3)2.6H2O and NH4(NCS) to form a unique octanuclear [Co(II)2-Co(III)2]2 interlocked, single braided 4 + 4 [2]catenane.

Photochemical reactions of (CO)2 (PPh3)MnC5H4Fe(CO)2C5H5 and (CO)2(PPh3)MnC5H4COFe(CO)2C5H5 with PPh3

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1977
The photochemical reactions of (CO)2(PPh3)MnC5H4Fe(CO)2C5H5 and (CO)2(PPh3)MnC5H4COFe(CO)2C5H5 with PPh3 gave the products of replacing the CO on the Fe atom by PPh3: respectively (CO)2(PPh3)MnC5H4Fe (CO)(PPh3)C5H5 and (CO)2(PPh3)MnC5H4COFe(CO)(PPh3)C5H5.

The linkage of CO₂and CO

Proceedings of the Physical Society, 1934
New calculations of Adel and Dennison make it possible to show that the ground level of CO2 arises adiabatically from C (p4 3P) + O (3P) + O (3P), or in other words that the linkage of the carbon atom to either of the oxygen atoms is exactly the same and is due to a pronounced p2=p4 bond (O=C=O).

[Rh2(μ-CO)(CO)2(η-indenyl)2] from solid state decarbonylation of the monomer (η-indenyl)-Rh(CO)2

Journal of Organometallic Chemistry, 1999
Abstract The complex [Rh 2 ( μ -CO)(CO) 2 ( η -indenyl) 2 ] was obtained as pure crystals by warming the solid monomer ( η -indenyl)-Rh(CO) 2 in vacuo at 50°C. The characterization of the dimer by spectroscopic and X-ray analysis is described.

2∞[Co{1,4-C6H4(CN)2}2{NTf2}2][SnI{Co(CO)4}3]2 – a 2D coordination network with an intercalated carbonyl cluster

Dalton Transactions, 2012
Dark red transparent crystals of [Co{1,4-C(6)H(4)(CN)(2)}(2){NTf(2)}(2)][SnI{Co(CO)(4)}(3)](2) are obtained by reacting SnI(4), Co(2)(CO)(8) and 1,4-C(6)H(4)(CN)(2) in the ionic liquid [EMIm][NTf(2)] (EMIm: 1-ethyl-3-methylimidazolium; NTf(2): bis(trifluoromethylsulfonyl)imide).

Caged CO₂ for the Direct Observation of CO₂‐Consuming Reactions

ChemBioChem, 2013
AbstractCO2‐consuming reactions, in particular carboxylations, play important roles in technical processes and in nature. Their kinetic behavior and the reaction mechanisms of carboxylating enzymes are difficult to study because CO2 is inconvenient to handle as a gas, exists in equilibrium with bicarbonate in aqueous solution, and typically yields ...
