Description / Table of Contents:
The First Metal Complex with Neutral 1,2-Bis(phenyltriazeno)-benzene as Ligand: Synthesis and Crystal Structure of [Cd{PhN3(H)C6H4N3(H)Ph}{PhN3C6H4N3(H)Ph}2][Cd{PhN3(H)C6H4N3(H)Ph}{PhN3C6H4N3(H)Ph}2] is obtained in aqueous ammonia by the reaction of CdSO4 with an excess of 1,2-bis(phenyltriazeno)benzene. It forms orange red, air stable prismatic crystals with the monoclinic space group P21/c and a = 1217.7(2); b = 2161.8(6); c = 2008.3(5) pm; β = 100.07(6)º; Z = 4. The compound is composed of mononuclear complexes in which the Cd atom is coordinated by one chelating bis(phenyltriazeno)benzene and two monodentate 1-phenyltriazenido-2-phenyltriazeno benzene anions in a distorted tetrahedral arrangement. The Cd - N distances are in the range of 220.7 to 239.7 pm.
Notes:
[Cd{PhN3(H)C6H4N3(H)Ph}{PhN3C6H4N3(H)Ph}2] entsteht in ammoniakalischer Lösung aus CdSO4 und einem Überschuß an 1,2-Bis(phenyltriazeno)benzol in Form orangeroter, luftstabiler Kristalle. Es kristallisiert monoklin in der Raumgruppe P21/c mit a = 1217,7(2); b = 2161,8(6); c = 2008,3(5) pm; β = 100,07(6)º; Z = 4. Die Verbindung bildet einkernige Komplexe, in denen das Cd-Kation von einem chelatartig gebundenen Bis(phenyltriazeno)benzol und zwei einzähnig koordinierenden 1-Phenyltriazenido-2-phenyltriazenobenzol-Anionen verzerrt tetraedrisch umgeben ist. Die Cd - N-Abstände liegen im Bereich zwischen 220,7 und 239,7 pm.
