    Notes: Abstract In a two-lever, food-reinforced drug-discrimination paradigm separate groups of rats were trained to discriminate either arecoline, pilocarpine or oxotremorine from saline. The discriminative cues of all three agonists were potently blocked by scopolamine, but only by 30–60 fold higher doses of methylscopolamine. The three agonists all suppressed overall response rate. These rate-suppressant effects were not blocked by scopolamine in doses which blocked the discriminative cues. In generalization tests, arecoline elicited selection of the drug-appropriate lever in all groups of trained animals. Pilocarpine was discriminated as drug by all pilocarpine-trained animals and by a majority of oxotremorine-trained animals, but was not significantly discriminated by the arecoline-trained group. Oxotremorine was discriminated by all oxotremorine-trained animals but only by some pilocarpine-trained animals, and was not significantly discriminated by the arecoline-trained group. Morphine, haloperidol, chlordiazepoxide, pentobarbital and nicotine were not generalized to any of the training drugs. The discriminative stimuli produced by the training drugs are therefore specific and exhibit properties indicative of an origin at central muscarinic receptors but may not be identical.

    Description / Table of Contents: Crystal Structures of Loellingite FeAs2 and of Pyrite RuTe2The structures of loellingite FeAs2 and pyrite type RuTe2 hitherto only known from powder measurements were redetermined by single crystal X-ray methods. Single crystals of FeAs2 (as large as 6 × 2 × 2 mm) were grown by CVD method with iodine in a temperature gradient of 800°C to 765°C, those of RuTe2 from a Te flux. The refinements of the structural parameters yielded a final R = 3.9% for 511 observed reflections (1 〉 2σI) of FeAs2 and R = 3.8% (3.7%) for 429 (410) reflections (I 〉 3σI) of RuTe2 (two experiments). For RuTe2, there are some intensities (even with I 〉 2σI) due to simultaneous diffraction.
    Notes: Die bisher nur aus Pulverdaten bekannten Strukturen der Verbindungen FeAs2 (Löllingit) und RuTe2 (Pyrit) wurden anhand von Einkristalldaten neu bestimmt. Die Darstellung der FeAs2-Einkristalle (Kantenlänge bis zu 6 mm) erfolgte durch Gasphasentransport mit Iod, die Einkristalle des RuTe2 wurden aus einer Tellurschmelze erhalten. Die Verfeinerung der Strukturparameter konvergierte beim FeAs2 für 511 beobachtete Reflexe (I 〉 2σI) bei R = 3.9% und beim RuTe2 für 429(410) beobachtete Reflexe (I 〉 3σI) bei 3,8% (3,7%) (zwei Kristalle). Einige Reflexe des RuTe2 mit I 〉 2σI sind auf Mehrfachreflexionen zurückzführen.
