    Description / Table of Contents: The Crystal Structure of tBu2P—P=P(Br)tBu2tBu2P—P=P(Br)tBu2 1 crystallizes in the monoclinic space group P21/c with a = 2 888.9(3), b = 972.16(10), c = 1 534.04(14) pm, β = 105.129(8)° and 8 formula units in the unit cell. The two independent P3-units in 1 form angles of 105.77° or 105.98°, resp. One P—P distance (220,4 pm) corresponds to a single bond, the other one (207.9 pm) to a double bond.
    Notes: tBu2P—P=P(Br)tBu2 1 kristallisiert monoklin in der Raumgruppe P21/c mit a = 2 888,9(3), b = 972,16(10), c = 1 534,04(14) pm, β = 105,129(8)° und 8 Formeleinheiten in der Elementarzelle. Die beiden unabhängigen P3-Einheiten in 1 sind gewinkelt (105,77° bzw. 105,98°). Die P—P-Abstände entsprechen mit 220,4 pm einer Einfachbindung bzw. mit 207,9 pm einer Doppelbindung.

    Description / Table of Contents: [Na · Triglyme]2[S(BH3)4]: a Salt of the New Anion Tetrakis(borane)sulfate(2- ). Crystal Structure and Theoretical Investigation of the StructureNa[H3B-m̈2-S(B2H5)] 1 is produced by the reaction between NaSH and THF · BH3, under dehydrogenation. 1 is also formed as the first 11B-NMR-spectroscopically detectable reaction product by the reaction between anhydrous Na2S and THF · BH3. Adducts of BH3 with the S2- ion are not detectable in THF. The anion [S(BH3)4]2- can however be obtained, by the addition of NaBH4 to 1 in diglyme or triglyme respectively: [Na  -  Triglyme]2[S(BH3)4] 2. 2 crystallizes in the monoclinic space group P21/n (Nr. 14). Structural data of 1 and 2 have been calculated by SCF methods. The anion of 2 may be viewed either as an adduct of B2H6 with S2-, or as a bridge substituted thia derivative of B2H7-; furthermore the anion of 2 is isoelectronic and isostructural with the SO42- ion.
    Notes: Bei der Reaktion zwischen NaSH und THF · BH3 entsteht unter H2-Abspaltung Na[H3B-m̈2-S(B2H5)] 1. 1 entsteht auch als erstes 11B-NMR-spektroskopisch nachweisbares Reaktionsprodukt bei der Reaktion zwischen wasserfreiem Na2S und THF · BH3. Addukte von BH3 an das S2--Ion lassen sich in THF als Lösungsmittel nicht nachweisen. Das neue Anion [S(BH3)4]2- kann jedoch durch Addition von NaBH4 an 1 in Diglyme bzw. Triglyme erhalten werden: [Na · L]2[S(BH3)4] 2. 2 kristallisiert monoklin in der Raumgruppe P21/n (Nr. 14). Aus SCF-Rechnungen erhielten wir die Strukturparameter für 1 und 2. Das Anion von 2 kann sowohl als Addukt von B2H6 an S2- als auch als brückensubstituiertes Thia-Derivat des B2H7--Ions aufgefaßt werden; ferner ist es isoelektronisch und isostrukturell mit dem SO42-- Ion.
