Self-Assembly of cis and trans Forms of the Copper(II) Complex with 1-Aminocyclopropane-1-carboxylate into Discrete Trimers in the Solid State

Abstract

A copper(II) complex with 1-aminocyclopropane-1-carboxylic acid assembles by apical Cu...O bonds and hydrogen-bonding interactions into discrete trimeric units that exhibit both cis and trans binding modes.

Characterization of Cu(II)-ACC Complexes and Conversion of the Bound ACC into Ethylene in the Presence of Hydrogen Peroxide. Detection of a Brown Intermediate at Low Temperature

“…We also obtained crystals of complex 2 that have been analyzed by X-Ray diffraction technique. However, the same structure was, shortly after, described by Judas and Raos [ 15 ]. In Table 1 , selected crystallographic data are reported for the two structures as obtained in our group.…”

“…The structure of 2 is presented on Figure 2 . It has been extensively described by Judas et al [ 15 ]. It consists in an original arrangement where the asymmetric unit is composed of a trimeric assembly of Cu(ACC) 2 complexes.…”

“…Here, we describe a more detailed study of this complex as well as the comparison with another copper(II)-ACC complex: [Cu(ACC) 2 ] 3 · 4H 2 O ( 2 ). Soon after its characterization in our laboratory, Judas and Raos [ 15 ] published a complete structural analysis of the latter complex (complex 2 ). We will present here the reactivity studies on 2 and compare the structural and spectroscopic data for the two complexes.…”

Theoretical analysis of apical bonding in copper(II) chelates with amino acids

“…In the data set we included all the crystal structures of copper(II) bis complexes with bidendate -amino acids. This includes the structures from the Cambridge Structural Database (Gillard et al, 1969;Van der Helm & Franks, 1969;Weeks et al, 1969;Stephens et al, 1977;Fawcett et al, 1979;Muhonen & Hamalainen, 1983;Hitchman et al, 1987;Calvo et al, 1991;Moussa et al, 1999;Rizzi et al, 2000;Casari et al, 2004;Versiane et al, 2005;Zhang et al, 2005) and a PhD thesis (Judaš, 2004). For visualization of the crystal structures and calculation of their geometric parameters, we used Mercury version 1.4.2 (Macrae et al, 2006; http://www.ccdc.cam.ac.uk/ free_services/mercury/downloads/Mercury_1.4.2/).…”

Single crystal electron paramagnetic resonance spectra of CuII ions in Cu(tyrosine)2

“…The interactions between amino acids and different metallic ions produce a variety of structures which go from mononuclear to polynuclear systems being mononuclear species or one dimensional chains the most common structures in this type of compounds [1][2][3][4][5][6][7][8][9][10][11][12][13].…”
