    Description / Table of Contents: K3BiSe3, Rb3BiSe3, and Cs3BiSe3 - Derivatives of the Th3P4 Structure TypeThe compounds K3BiSe3, Rb3BiSe3, and Cs3BiSe3 were synthesized by heating mixtures of Bi2O3 and the respective alkalicarbonate in a stream of hydrogen saturated by selenium at 850°C. Thin crystals of the compounds appear red in transmitted light. They crystallize isostructural with Na3AsS3, space group P213, lattice constants a = 9.771(5) Å, a = 10.161(3) Å, and a = 10.587(5) Å for K3BiSe3, Rb3BiSe3, and Cs3BiSe3, respectively. The Na3AsS3 structure type is a derivative of the Th3P4 structure type.
    Notes: Die Darstellung der Verbindungen K3BiSe3, Rb3BiSe3 und Cs3BiSe3 gelang durch Umsetzungen von Bi2O3 mit dem entsprechenden Alkalicarbonat in einem mit Selen beladenen Wasserstoffstrom bei 850°C. Die Verbindungen erscheinen im Durchlicht rot und kristallisieren im Na3AsS3-Typ (Raumgruppe P213) mit den Gitterkonstanten a = 9,771(5) Å für K3BiSe3, a = 10,161(3) Å für Rb3BiSe3 und a = 10,587(5) Å für Cs3BiSe3. Es handelt sich um Substitutionsderivate des Th3P4-Typs.

    Description / Table of Contents: About Alkali Seleno Bismuthates (III), with a Comment Regarding the Th3P4 Structure TypeThe synthesis and X-ray single crystal structure determination of the ternary selenides Rb3BiSe3, Cs3BiSe3, and RbK2BiSe3 are described. The compounds were synthesized via a reaction of Bi2O3 with the alkali carbonate in a selencharged hydrogen stream at 850°C. They crystallize in the Na3AsS3 structure type (space group P213). In the discussion of the structure, the aristotypic Th3P4 structure is included.
    Notes: Es wird über die Darstellung und Einkristallstrukturbestimmung der ternären Selenide Rb3BiSe3, Cs3BiSe3 und RbK2BiSe3 berichtet. Die Synthese gelingt durch Umsetzungen von Bi2O3 mit dem entsprechenden Alkalicarbonat in einem mit Selen beladenen Wasserstoffstrom bei 850°C. Die Verbindungen kristallisieren im Na3AsS3-Typ (Raumgruppe P213). In die Strukturdiskussion wird der Th3P4-Typ als Aristotyp mit einbezogen.

    Description / Table of Contents: Preparation and Crystal Structure of Rb2Ni3Se4The compound Rb2Ni3Se4 was synthesized by heating a mixture of rubidium carbonate, nickel and selenium at 850°C in an atmosphere of hydrogen. The compound has a golden lustre and crystallizes with the K2Pd3S4-type structure; a = 10.555(3) Å, b = 27.588(6) Å, c = 6.031(6) Å, Z = 8, Fddd (No. 70).The structure can be described as a stacking of layers of the composition Rb2Ni3Se4 with a stacking sequence abcd. The electrostatic part of lattice energy (MAPLE) will be discussed for compounds of the compositions A2M3X4 (A K, Rb, Cs; M Ni, Pd, Pt and X S, Se).
    Notes: Die Darstellung von Rb2Ni3Se4 gelang durch Umsetzung von Rubidiumcarbonat, Nickel und Selen in einem Wasserstoffstrom bei 850°C. Die goldfarbig glänzende Verbindung kristallisiert im K2Pd3S4-Typ; a = 10,555(3) Å, b = 27,588(6) Å, c = 6,031(6) Å, Z = 8, Fddd (Nr. 70).Die Struktur läßt sich als Stapelung von Schichten der Zusammensetzung Rb2Ni3Se4 mit der Stapelfolge abcd beschreiben. Der elektrostatische Anteil der Gitterenergie (MAPLE) wird für Verbindungen des Typs A2M3X4 (mit A K, Rb, Cs; M Ni, Pd, Pt und X S, Se) diskutiert.
