    Notes: Summary A study was carried out involving 134 neurotic-depressive inpatients (according to ICD-9) treated with cognitive behaviour therapy and in a subgroup additionally with antidepressants. Using standardized rating instruments, a large set of potential predictor variables was tested. After cross-validation according to the splithalf technique, only very few of these proved to be suitable as predictors for the main outcome criteria. These predictors included certain aspects of social functioning before index admission, intensity of depressive symptoms at admission and the degree of self-evaluated mood disturbances three weeks after admission. Several predictors known from the literature could not be reproduced in this study, demonstrating the well-known instability of most predictor findings. On the other side, the predictor profile of the neurotic-depressive patients was quite similar to that found in endogenous depressives, a result which might — together with other findings, such as the response of neurotic depressives to antidepressants — question the traditional subclassification of functional depressive states into these subgroups.

    Description / Table of Contents: Lattice Vibration Spectra. LXXVI. On Basic Copper Salts  -  Crystal Structure, IR and Raman Spectra of Cu2(OH)3NO2Single-crystal X-ray as well as IR and Raman data of Cu2(OH)3NO2 are presented and discussed with respect to an order-disorder (OD) phase transition and the strength of hydrogen bonds. Cu2(OH)3NO2 crystallizes pseudosymmetrically in the monoclinic space group P21/m (Z = 2, a = 562.22(4), b = 605.94(5), c = 663.55(4) pm and β = 95.415(5)°) forming a layered structure of edge-connected, elongated CuO6 octahedra (final R value 2.5% for 1047 symmetry averaged reflections with I ≥ 2.5 μ1). The NO2- ions are on a split position with dynamic disordering at ambient temperature. On temperature lowering the disorder is frozen out with a symmetry decrease to space group P21. The disorder of the NO2- ions causes four different arrangements of OH(2)- with different strengths of the H…O hydrogen bonds present OD stretching modes in the spectra of isotopically dilute samples 2628, 2535, 2435, and 2343 cm-1 at 90 K. The OH(1)- ions form weak H…N H-bonds to the lone-pair of the nitrogen atoms of the NO2- ions (vOD 2563 cm-1).
    Notes: Die Kristallstruktur sowie die IR- und Raman-Spektren von Cu2(OH)3NO2 werden mitgeteilt und im Hinblick auf eine Ordnungs-Unordnungs(OD)-Phasenumwandlung sowie die Stärke der vorhandenen Wasserstoffbrücken diskutiert. Das basische Nitrit kristallisiert pseudosymmetrisch in der monoklinen Raumgruppe P21/m (Z = 2, R = 2,5%, 1047 symmetriegemittelte Reflexe mit 1 〉 2,5 μ1). Cu2(OH)3NO2 bildet eine Schichtenstruktur kantenverknüpfter, gestreckter CuO6-Oktaeder. Die Nitritionen befinden sich auf einer Splitlage mit dynamischer Fehlordnung bei Raumtemperatur. Bei niedrigeren Temperaturen friert die Fehlordnung unter Bildung von NO2--Zick-Zack-Ketten und Symmetrieerniedrigung zu P21 aus. Aufgrund der Fehlordnung der NO2--Ionen ergeben sich für die OH(2)--Ionen vier verschiedene Anordnungen mit entsprechend unterschiedlich starken H-Brücken (H…O). Die OH(1)--Ionen bilden H…N-Wasserstoffbrücken zum freien Elektronenpaar des N-Atoms der NO2--Ionen.
