    Description / Table of Contents: Summary The crystal structure of the new mineral warikahnite, Zn3[(H2O)2|(AsO4)2], was determined from diffractometer data and refined toR=0,038 for 3428 observed independent reflections. Warikahnit is triclinic, $$P\bar 1$$ , witha=6.710(1),b=8.989(2),c=14.533(2) Å, α=105.59(1), β=93.44(1), γ=108.68(1)°,Z=4. The crystal structure of warikahnite contains 6 different coordination polyhedra of zinc with the coordination numbers 6,5 and 4 and with 5 different combinations of ligand. The hydrogen bonds are discussed on the basis of charge balance and IR spectra.

    Description / Table of Contents: Crystal and Molecular Structure of N,N′-DiformylanilineN,N′-diformylaniline crystallizes in the monoclinic space group P21/n with Z = 8 and a = 856.1(2), b = 1277.6(3), c = 1306.1(3) pm, β 92.29(2)°, V = 1427.4(5) · 106 pm3. As shown by X-ray structure determination (2642 symmetry independent reflections, RW = 0.034) the molecule exists in two enantiomeric forms. The molecular structure can be described by two planes; the angle between the plane of the aromatic ring and the plane of the N,N′-diformylamino group is 70.1 resp. 108.3°. The results are compared with those obtained for other derivats.

Nach den Ergebnissen der Röntgenstrukturanalyse (2642 symmetrieunabhängige Reflexe; RW = 0,034) existiert das Molekül in zwei enatiomeren Formen. Die Molekülstruktur kann durch zwei Ebenen beschrieben werden; der Winkel zwischen der Ebene des Aromaten und der durch die N,N′-Diformylaminogruppe gelegten Ebene beträgt 70,1 bzw. 108,3°.

    Description / Table of Contents: Acyl- and Alkylidenephosphines. XXVIII. Synthesis and Structure of 1,3-Dibenzyl- and 1,3-Diethyl-2,4-bis(phenylimino)-1,3-diphosphetaneCatalyzed by small amounts of solid sodium hydroxide, the adducts 1a and 1b formed from benzyl- or ethylbis(trimethylsilyl)phosphine and phenylisocyanate, react at +20°C slowly to give hexamethldisiloxane and oligomeric [(phenylimino)methylidene]phosphines. In different solvents the benzyl compound was found to exist only as a mixture of [N,N′-(E)/(Z)]-isomeric 2,4-bis-(phenylimino)-1,3-diphosphetanes 2a with their alkyl groups at the phosphorus atoms in trans position, whereas in case of the ethyl derivative 2b a second pair of [N,N′-(E)/(Z)]-isomeric dimers with their substituents in cis position and two trimeric forms (3b and 4b) could be detected in cyclopentane. [N,N′-(E)]-1r,3t-dibenzyl- (2a) and [N,N′-(E)]-1r,3t-diethyl-2,4-bis(phenylimino)-1,3-diphosphetane 2b isolated from 1,2-dimethoxyethane or cyclopentane, crystallize in the monoclinic space group P21/c or P21/n, resp., with following dimensions of the unit cell determined at temperatures of measurement of +20 ± 3°C/-130 ± 3°C: a = 2145.4(1)/569.3(1); b = 568.1(2)/719.1(2); c = 1960.2(2)/2042.6(4) pm; β 99.43(1)°/95.03(2)°; Z = (2+2) and 2, resp. X-ray structure determinations (Rw = 0.034/0.041) show both molecules to be centrosymmetric. Characteristic rounded bond lengths (pm) and angles (°) are: endocyclic P—C 185/184; C—P—C 82/81; P—C—P 98/99; exocyclic P—C 186/184; C=N l27/127; C=N—C 121/11.
    Notes: Unter der Katalyse von wenig festem Natriumhydroxid setzen sich die aus Benzyl- oder Ethylbis(trimethylsilyl)phosphan und Phenylisocyanat gebildeten Addukte 1a und 1b bei +20°C langsam zu Hexamethyldisiloxan und oligomeren [(Phenylimino)methyliden]phosphanen um. Während die Benzyl-Verbindung in unterschiedlichen Lösungsmitteln nur als Gemisch aus [N,N′-(E)]- und [N,N′-(Z)]-isomerem 2,4-Bis(phenylimino)-1,3-diphosphetan 2a mit den beiden Alkylgruppen an den Phosphoratomen in trans-Stellung vorliegt, findet man bei dem in Cyclopentan gelösten Ethyl-Derivat 2b ein weiteres [N,N′-(E)/(Z)]-isomeres Dimerenpaar mit zueinander cisständigen Substituenten sowie die beiden trimeren Formen 3b und 4b. Die aus 1,2-Dimethoxyethan oder Cyclopentan isolierten Verbindungen [N,N′-(E)]-1r,3t-Dibenzyl- (2a) und [N,N′-(E)]-1r,3t-Diethyl-2,4-bis(phenylimino)-1,3-diphosphetan 2b kristallisieren monoklin in der Raumgruppe P21/c bzw. P21/n mit folgenden, bei Meßtemperaturen von +20 ± 3°C/-130 ± 3°C bestimmten Abmessungen der Elementarzelle: a = 2145,4(1)/569,3(1); b = 568,1(2)/719,1(2); c = 1960,2(2)/2042,6(4) pm; β 99,43(1)°/95,03(2)°; Z = (2+2) bzw. 2. Nach den Ergebnissen von Röntgenstrukturanalysen (RW = 0,034/0,041) weisen die Moleküle Inversionszentren auf. Charakteristische gemittelte Bindungslängen (pm) und -winkel (°) sind: endocycl. P—C 185/184; C—P—C 82/81; P—C—P 98/99; exocycl. P—C 186/184; C=N 127/127; C=N—C 121/11.
