    Notes: Summary The influence of quinidine 750 mg per day for one week on serum digoxin concentration (SDC) was evaluated in digitalized anuric patients on chronic haemodialysis. During quinidine administration the SDC increased markedly, from 0.84±0.37 to 1.58±0.72 ng/ml (p〈0.01), a comparable effect to that reported previously in patients with normal renal function. Neither in vitro nor in vivo did quinidine alter the serum protein binding of digoxin. The increase in SDC in anuric patients indicates a decrease in the extrarenal clearance of digoxin, which means that mechanisms other than of renal origin are also involved in the interaction of quinidine and digoxin. There was great interindividual variability in the extent of the quinidine-induced rise in SDC. Regardless of the state of renal function, careful monitoring of digitalized patients seems mandatory once quinidine treatment is initiated.

Rhombohedral 12 L Stacking Polytypes of Type Ba3LaBIIReVIIWVI□O12 with BnII = Mg, Co, Ni, Cu, ZnThe rhombohedral 12L perovskites with cationic vacancies of type Ba3LaBIIReW□O12 with BII = Mg, Co, Ni, Cu, Zn are isotypic. According to intensity calculations on powder patterns of Ba3LaZnReW□O12 the series crystallize in the space group R3m with the sequence (hhcc)3; the refined, intensity related R′ value is 5.7%. The octahedral net consists of blocks of three face connected octahedra with central void (ReW□O12 units), which are linked via common corners through single octahedra, occupied by zinc.

    Description / Table of Contents: Mixed-valent Perovskites of the Type Ba3BIIIPtRuO9Compounds of type Ba3BIIIPtRuO9 - with a mean oxydation state of the noble metals of +4.5 - crystallize with BIII = Gd—Lu, Y in a variant of hexagonal BaTiO3 type with ordered cationic distribution. Intensity calculations on powder data of Ba3YPtRuO9 (a = 5.888; c = 14.70 Å) gave in the space group P63/mmc (sequence (hcc)2) a refined, intensity related R′ value of 5.9%. With BIII = Eu the lattice is monoclinic and for BIII = Sm, Nd, La triclinic distorted.

    Description / Table of Contents: On Hexagonal Perovskites with Cationic Vacancies. XXVII. Systems Ba4-xSrxBIIRe2□O12, Ba4B1-xIICaxRe2□O12, and Ba4-xLaxBIIRe2-xWx□O12 with BII = Co, NiIn the systems Ba4-xSrxBIIRe2□O12, Ba4B1-xIICaxRe2□O12 and Ba4-xLaxBIIRe2-xWx□O12 (BII = Co, Ni) hexagonal perovskites with a rhombohedral 12 L structure (general composition A4BM2□O12; sequence (hhcc)3; space group R&3macr;m) are observed. With the exception of Ba4NiRe2□O12 the octahedral net consists of BO6 single octahedra and M2□O12 face connected blocks (type 1). In type 2 (Ba4NiRe2□O12) the M ions are located in the single octahedra and in the center of the groups of three face connected octahedra. The two outer positions of the latter are occupied by B ions and vacancies in the ratio 1:1.The difference between type 1 and 2 are discussed by means of the vibrational and diffuse reflectance spectra.
    Notes: In den Systemen Ba4-xSrxBIIRe2□O12, Ba4B1-xIICaxRe2□O12 und Ba4-xLaxBIIRe2-xWx□O12 (BII = Co, Ni) treten hexagonale Perowskite mit rhomboedrischer 12 L-Struktur (allgemeine Zusammensetzung A4BM2□O12; Sequenz (hhcc)3; R.G. R&3macr;m) auf, deren Oktaedergerüst - mit Ausnahme von Ba4NiRe2□O12 - aus BO6-Einzeloktaedern und M2□O12-Dreiergruppen aufgebaut ist (Typ 1). Im Typ 2 (Ba4NiRe2□O12) befinden sich die M-Ionen dagegen in den Einzeloktaedern und im Zentrum des Dreierblocks, dessen beiden äußeren Positionen mit B-Kationen und Fehlstellen im Verhältnis 1:1 besetzt sind.Die Unterschiede zwischen Typ 1 und 2 werden an Hand der Schwingungsspektren und diffusen Reflexionsspektren diskutiert.
