The angles between the C 5(ring)-centroid and the Co Co line are ca. 150 and 167° in II and V, respectively, which reflects the influence of the bridging hydride ligand in the cationic complex.doi:10.1016/0022-328X(85)88038-4A. KüElsevier B.V.Journal of Organometallic Chemistry...
self-assemblyX-ray diffractionTaking turns: Reaction of an anionic bis-phosphine with Cu+ produces a monomeric complex that crystallizes as a dimeric helicate (see picture). The helicate dissolves again in non-coordinating solvents, but disassembles upon addition of a donor solvent. The observed...
The intense bands at 2848 and 2918 cm −1 are assigned to symmetric ν s(CH 2) and asymmetric ν a(CH 2) stretching vibrations of methylene groups. These peaks suggest that the alkyl chains in TOC are nearly in all-trans conformational state. The presence in the infrared spectra of ...
