“…The X-ray diffraction pattern of the starting material CuO could be indexed on the standard tenorite unit cell in C2/c, 48 (14)1. The b-Cu 2 Cr-Cl final product could be successfully indexed on a R% 3m cell with a = 3.111(1) Å and c = 23.153(7) Å, again in excellent agreement with the literature.…”

The formation of the layered double hydroxide [Cu 2 Cr(OH) 6 ]ClÁyH 2 O from the reaction between CuO and aqueous CrCl 3 Á6H 2 O was explored using synchrotron X-ray diffraction and ex situ analyses. The use of hard X-rays permitted time-resolved in situ studies to be performed as the reaction proceeded under a range of conditions. Additional information was obtained from ex situ experiments in which aliquots of the reaction mixture were removed, quenched, and subsequently analysed by laboratory X-ray diffraction, IR, UV-visible, and atomic emission spectroscopies. On the basis of these data, it is proposed that the reaction involves three steps. First, the solid CuO starting material is hydrolysed to give Cu(OH) 2 chains, releasing Cu 2+ ions into solution. The Cu hydroxide chains subsequently condense with aqueous Cr 3+ species, Cl À ions and water molecules to give a hydrated form of the LDH. This material then extrudes some water to form a phase with a reduced interlayer spacing.

“…Interestingly, CuO-which has been studied as a model parent compound for the HTS cuprates due to its simple stoichiometry [6,7]-does not contain copper oxide layers. Its low-symmetry monoclinic tenorite structure consists of crossed ribbons of edgesharing CuO 4 plaquettes [8], and its magnetic excitations have 1D character (spinons) [9,10].…”

We investigate by angle-resolved photoemission the electronic structure of in situ grown tetragonal CuO, a synthetic quasi-two-dimensional edge-sharing cuprate. We show that, in spite of the very different nature of the copper oxide layers, with twice as many Cu in the CuO layers of tetragonal CuO as compared to the CuO 2 layers of the high-T c cuprates, the low-energy electronic excitations are surprisingly similar, with a Zhang-Rice singlet dispersing on weakly coupled cupratelike sublattices. This system should thus be considered as a member of the high-T c cuprate family, with, however, interesting differences due to the intralayer coupling between the cupratelike sublattices.
