Structural chemistry of organocopper(I) compounds

catena-Bis(phosphinato)(2,2'-bipyridyl)manganese(II)

“…The bond lengths in the MnN20 4 group are also normal. The inter-ring distance [C(1)-C(lli)] in 2,2'-bipyridyl is near the upper end of the range of distances found in numerous studies of bipyridyl complexes (Camus, Marsich & Nardin, 1977) but is close to the distance in the free ligand (1.50 A; Merritt & Schroeder, 1956). The greatest distance of a ring atom from the mean plane of a pyridyl ring is 0.015 ,/~ [C(2), the atom most closely involved in interchain contacts] and the Mn atom lies 0.043 /k from this plane.…”

Chelating and bridging bis(diphenylphosphino)aniline complexes of copper(I)

“…However, the Cu-Br distances were quite unsymmetrical and only the shorter distances are shown bonded in the ORTEP plot. The analogous bromide tetramer of dppm ligand had a Cu-Cu distance of 3.189 Å for dppm bridged copper atoms [29,30] which was longer by almost 0.41 Å compared to the Cu-Cu distance in the PNP bridged copper centers of the diphosphinoamine complex.…”

Etude structurale de Cu2CI2.NCHC = CH2

“…Un article r+cent (Camus, Nardin & Randaccio, 1975) a prtsent~ une interpr&ation structurale des cas observ+s en partant de l'assemblage t&ra+drique de CuX pur. Lorsque la taille du ligand est relativement petite, on obtient, avec m/n = 1, des chMnes doubles infinies (Cu2X2)oo (Brown & Dunitz, 1960;Moers, Bosman & Beurskens, 1972).…”
