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 ...
copperhelical structuresphosphane ligandsself-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 additi...
