    Description / Table of Contents: Crystalline Adducts of 7, 7, 8, 8-Tetracyanoquinodimethane (TCNQ) with Bis(1,2-benzoquinonedioximato)nickel(II) and palladium(II): Synthesis and StructureSolid adducts of stoichiometry Ni(BCD)2 · TCNQ and Pd(BCD)2 · TCNQ were obtained by reacting bis(1,2-benzoquinonedioximato)nickel(II) and palladium(II) with TCNQ. The compound Pd(BCD)2 · TCNQ crystallizes in the triclinic space group P1 with cell parameters a = 10.251(3) Å, b = 7.843(3) Å, c = 7.328(2) Å, α = 105.54° (3), β = 83.63° (3), γ = 92.28° (3), Z = 1, Dx = 1.72 g · cm-3. The structure was solved by standard Patterson and Fourier methods and refined by the least squares technique to a R-value of 6.4% based on 2230 observed independent reflexions. The structure consists of parallel stacks of alternating TCNQ and Pd(BCD)2 molecules which are planar and electrically neutral. The normals of the molecular planes are inclined with respect to the stacking direction.
    Notes: Bei der Reaktion von Bis(1,2-benzochinondioximato)-nickel(II), [Ni(BCD)2] und -palladium(II), [Pd(BCD)2] mit TCNQ wurden die kristallinen Addukte Ni(BCD)2 · TCNQ und Pd(BCD)2 ·TCNQ erhalten. Die beiden Verbindungen sind isomorph und kristallisieren in der triklinen Raumgruppe P1. Die Struktur der Palladiumverbindung (a = 10,251(3) Å, b = 7,843(3) Å, c = 7,328(2) Å, α = 105,54°(3), β = 83,63°(3), γ = 92,28° (3), Z = 1, Dx = 1,72 g·cm-3) wurde mittels Patterson- und Fouriersynthesen bestimmt. Die Verfeinerung nach der Methode, der kleinsten Quadrate lieferte mit allen 2 230 beobachteten unabhängigen Reflexen einen R-Wert von 6,4%. Die Struktur besteht aus parallelen Stapeln von sich abwechselnden TCNQ- und Pd(BCD)2-Molekülen, die eben und ungeladen sind. Die Normalen der Molekülebenen sind zur Stapelrichtung geneigt.
