“…X-Ray structural studies have revealed tetrahedral (1)(2)(3)(4)(5), pseudo-tetrahedral (6), a tetrahedral-trigonal dimer (7), dimeric (3), tetrameric (3), and polymeric (8) molecules including compounds with halogen (5,7) and azide (4) bridges. Although several of the above complexes can be synthesized by the reduction of the appropriate copper(I1) salt with the tertiary phosphine, the scope of this preparative method has not been explored.…”

Copper(1) nitrate complexes of the types LZCuN03, L3CuN03, and L4CuN03 (L = tertiary phosphine) have been synthesized by reduction of copper(I1) nitrate with tertiary phosphines. Infrared spectra and single crystal X-ray measurements indicate the presence of bidentate nitrate in LZCuNO,, monodentate nitrate in L3CuN03, and ionic nitrate in L4CuN03. The single crystal X-ray structure of nitratobis (tricyclohexylphosphine)copper(I) is reported. C U O~N ( P C , , H~~)~ crystallizes in the monoclinic space group C2/c with a = 18.18(1) A, b = 9.240(6) A, c = 22.41(2) A, and = 96.57(5)". The structure was solved by the heavy atom method and refined with isotropic thermal parameters to an R of 0.14. The copper atom is tetrahedrally coordinated by two phosphorus atoms and two oxygen atoms of a bidentate nitrate group. The P-Cu-P angle (140(1)") and Cu-P bond lengths (2.29(1) A) are the largest reported for tetrahedral copper complexes.A facile synthetic route to acetylacetonatobis(phosphine)copper(I) complexes is also described.La reduction du nitrate de cuivre (11) avec des phosphines tertiaires (L) a permis de synthetiser des complexes du cuivre(1) de formules L,CuN03, L3CuN03 et L4CuN03. La spectroscopic infrarouge et I'ttude de monocristaux par rayons X indiquent que le groupe nitrate est bicoordine dans LZCuNO,, monocoordinC dans L3CuN03 et ionique dans L4CuN03. On a determine au moyen de la diffraction des rayons X par monocristaux la structure du nitratobis(tricyclohexylphosphine)cuivre(l). C u 0 3 N (PC,sH33)z cristallise dans le systeme monoclinique, groupe spatial C2/c: a = 18.18 (1) A, b = 9.240 (6) A, c = 22.41 (2) A et = 96.57 (5)". On a applique la methode de l'atome lourd et, utilisant des facteurs thermiques isotropes, on a obtenu apres affinement un facteur R tgale a 0.14. Deux atolnes de phosphore et les deux atomes d'oxygene d'un groupe nitrate bicoordine assurent a I'atome de cuivre une coordination tetraedrique. L'angle P-CU-P (140(1)") et la longueur de liaison Cu-P (2.29 (1) A) sont les plus grandes qu'on ait rapport& pour des composes tetraedriques du cuivre.On prksente Cgalement une methode commode pour la synthese des complexes acetylacetonatobis-(phosphine)cuivre(I).

“…Messmer & Palenik (1969) reported the nitrate interaction with copper(I) in bis(triphenylphosphine)copper(I) nitrate, where the P--Cu--O bond angle is 126.0 °. A silver(I)-oxygen interaction also has been reported for [Ag(PPh3)2]NO3, P--Ag--O 117.2 ° (Barron, Dyason, Healy, Engelhardt, Skelton & White, 1986).…”

“…We have used the 1 H chemical shift variation of each signal with respect to those of the free ligand (Dd) as a parameter to deduce the mode of coordination of CQ to the metal. It has been previously shown by us [14][15][16][17][18][19][20][21][22][23] and by others [24] that the largest variations are always observed for the protons located in the vicinity of the N-atom attached to the metal.…”
