“…As usual in square pyramidal copper complexes, the Cu-apex distance Cu(1)-O(13a), 2.371(2) Å , is longer than the bond lengths in the base [Cu(1)-O(13) ϭ 1.924(1) Å ] due to the ... σ * (dz 2 ) 2 σ * (dx 2 -y 2 ) 1 configuration of the copper(II) ion. The axial Cu-O distance is similar to those found in other dimers with asymmetric alkoxido bridges [30]. The basal Cu-O distance and the Cu-N distances [1.987(1)Ϫ2.017(1) Å ] are within the usual range for complexes of copper(II) with chelating 2,2Ј-bipyridine, bridging alkoxido and non-bridging carboxylato ligands [29].…”

Three new members of the copper/carboxylato/heterocyclic diimine family, namely [Cu(GLYO)(2,2Ј-bipy)] 2 · nH 2 O (n ϭ 4 (1) or 6 (2), H 2 GLYO ϭ glycolic acid, 2,2Ј-bipy ϭ 2,2Ј-bipyridine) and {[Cu(AcO) 2 (4,4Ј-bipy)] · 3H 2 O} n (3) (AcO ϭ acetato, 4,4Јbipy ϭ 4,4-bipyridine), have been synthesized and characterized by IR and electronic absorption spectroscopy, and the crystal structures have been determined by single crystal X-ray analysis. 1 and 2 are composed of discrete dinuclear units in which each Cu II atom is coordinated in a square pyramidal arrangement to the two nitrogen atoms of a bipyridine ligand, to bridging non-carboxy oxygen atoms belonging to two glycolato ligands, and to one of the carboxy oxygen atoms of one of these glycolato ligands. The Cu··Cu distance is 3.0666(5) Å . Compound 3 consists of linear chains of dinuclear units in which each Cu II is coordinated to one non-bridging monodentate acetato ligand, to two acetato ligands

“…To examine Cu I 3 =O 2 chemistry Karlin and co-workers synthesized the ligand 30 [139]. The trinuclear copper(I) complex reacted with O 2 at À80°C in CH 2 Cl 2 /CH 3 CN (9:1) to give the hexanuclear cluster (see below) in which the xylyl ring has been hydroxylated (see Fig.…”

“…When these R groups provide additional donor atoms, several copper ions can be bound by the ligand; for example, reaction of tren with picolyl chloride or 2-vinylpyridine allowed the isolation of trinuclear copper complexes. [91,92] It is also possible to chemically alter tren without modifying all three arms. An example where only one amine arm was altered has been described by Spiccia and co-workers (L 9 , Scheme 5).…”

Efforts to model the reactions of copper enzymes with dioxygen with low molecular weight complexes have been quite successful during recent years. Guided by Nature, intriguing model systems for the active sites of such proteins have been developed. In the course of these investigations, it has been discovered that a whole variety of copper−dioxygen adducts form when simple copper(I) complexes are oxidized with dioxygen. The course of these reactions depends on the temperature, the ligands present, and the solvent. The effects of these parameters (especially the effect of ligand modification) on the reactivity of copper(I) complexes towards dioxygen are discussed in detail in this review.
