Socially anxious children may not necessarily lack social skills. Rather, their deficits may relate to nervousness and appraisals of their skills. Treatment programmes for these children should take care to assess social skills carefully before prescribing social skill remediation, and should consider employing a cognitive element to tackle negative misperceptions of subjective social skill.
Crystals of the title compound are monoclinic, space group C2/c, with dimensions a = 26.04, b = 9.24, c = 9.45 A, p = 94.25". The structure w a s solved by Fourier methods and the molecular parameters refined by full-matrix least-squares calculations to R 0.102 for 1681 independent reflexions. The copper atom lies on the crystallographic centre of symmetry with Cu-O(acetate) I .976 and Cu-N 2.052 A. Distorted octahedral co-ordination around the copper atom is completed by bridging water molecules, Cu-O(water) 2.595 A, which are shared by adjacent octahedra. The remaining water molecules. which are not co-ordinated to the copper atom, form a hydrogen-bonded chain. The single-crystal e.s.r. spectrum and powder magnetic susceptibilities over the temperature range 80-300 K are discussed in terms of the structure. The magnetic susceptibilities of the aniline and p-toluidine adducts of C U ( B U O ~) ~ and Cu(PrO,), are also reported and discussed.STUDIES of copper(I1) carboxylate compounds have shown that the magnetic properties depend upon the nature of the carboxylic acid and also on the nature of comparing the behaviour of the magnetic susceptibilities over a temperature range of compounds of unknown structure with similar measurements on compounds with known dimeric structures, many of these carboxylate compounds have been assigned as dimers. From the magnetic data the singlet-triplet separations, 2J, in these dimers have been found to fall in the range 250-350 cm-l, and the values of p,ff. at 300 K to be ca. 1-4BM. In addition to these compounds with low values of petf. there are a number of systems with p,ff. at 300 K in the range 1.6-1.8 BM, the magnetic susceptibilities of which do not conform to the behaviour expected for monomeric copper(I1) compounds ; e.g. di-a-naphthoatocopper and dibutyratocopper-aniline.3 The behaviour of the magnetic susceptibilties over a temperature range of this latter class of compounds can be fitted to the binuclear model suggested by Bleaney and Bowers,ll and on this basis they are assumed to be binuclear. This interpretation leads to singlet-triplet separations which are (160 cm-l. Attempts have been made to correlate these variations in the singlettriplet separations in terms of the relative-donor and -acceptor properties of the carboxylate and adduct ligands, but without a great deal of success.
The single-crystal polarised electronic spectra, e.s.r., and magnetic anisotropy of tetra-(6-aminohexanoic acid)copper(l1) diperchlorate are reported. These properties are interpreted by use of a point-charge crystal-field model and are seen to be consistent with the relative orbital energies, dxy > dxe-ya > d, Z > d,,,. The crystal-field parameters obtained are shown to agree closely with those for CaCu(AcO),,GH,O when allowance is made for the different Cu-0 distances involved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
