Abstract
Abstract Ethynyl (tertiary phosphine) copper(I) complexes, RC→CCu(PR′ 3 ) n , are dimeric in nitrobenzene and rather more associated in benzene when n = 1; they are monomeric when n = 2. One unstable complex with n = 3 was also prepared. Infra-red spectra indicate strong interaction between metal and acetylenic orbitals in all the complexes, though not so strong as in the polymers (RC→CCu) χ . Some diacetylenic complexes PhC→C·C→CCu(PR′ 3 ): are also described, and crystalline (PhC→C·C→ CCu) 2 (PEt 3 ) 3 probably has a structure closely related to that of (PhC→CCuPMe 3 ) 4 which was shown to contain a chain of four linked copper atoms.
