Binary and ternary copper (I) complexes with 1,5-cyclooctadiene (cod), (Cu(cod){sub 2})ClO{sub 4} (1) and (Cu(cod)(bpy))PF{sub 6} (2) (bpy = 2,2{prime}-bipyridine) have been prepared. The crystal structures have been determined by using single-crystal X-ray diffraction methods. The geometry about the Cu atom coordinated to the four olefinic moieties of the two cod molecules is quasi-tetrahedral in 1. The Cu-C(olefin) distances of 2,27 {angstrom} (average) are significantly longer than those found for copper (I) olefin complexes, and the C{double bond}C bond distances of 1.33 {angstrom} (average) of the coordinated cod are almost the same that of free cod. On the basis of the C{double bond}C distance, the stretching frequencies of the C{double bond}C bonds and the {sup 1}H NMR chemical shifts of the olefinia protons, the Cu-olefin bonds in 1 were concluded to be dominated by {sigma} donation from the olefinic moiety to the copper. The geometry about the Cu atom coordinated to two nitrogen atoms of boy and two olefinic moiety of the cod molecule are significantly shorter than those of the other olefinic moiety (2.44 {angstrom} (average). In response to this, the C{double bond}C distance (1.36 (1) {angstrom}) of the former is longer than that (1.33) (1) {angstrom}) of the latter. 32 refs., 5 figs., 6 tabs.
