Abstract

en

The crystal structures of the monomeric palladium(II) azide complexes of the type L2Pd(N3)2 (L = PPh3 (1), AsPh3 (2), and 2-chloropyridine (3)), the dimeric [(AsPh4)2][Pd2(N3)4Cl2] (4), the homoleptic azido palladate [(PNP)2][Pd(N3)4] (5) and the homoleptic azido platinates [(AsPh4)2][Pt(N3)4] · 2 H2O (6) and [(AsPh4)2][Pt(N3)6] (7) were determined by X-ray diffraction at single crystals. 1 and 2 are isotypic and crystallize in the triclinic space group P1. 1, 2 and 3 show terminal azide ligands in trans position. In 4 the [Pd2(N3)4Cl2]2– anions show end-on bridging azide groups as well as terminal chlorine atoms and azide ligands. The anions in 5 and 6 show azide ligands in equal positions with almost local C4h symmetry at the platinum and palladium atom respectively. The metal atoms show a planar surrounding. The [Pt(N3)6]2– anions in 7 are centrosymmetric (idealized S6 symmetry) with an octahedral surrounding of six nitrogen atoms at the platinum centers.

Die Kristallstrukturen von (PPh3)2Pd(N3)2, (AsPh3)2Pd(N3)2, (2-Chloropyridin)2Pd(N3)2, [(AsPh4)2][Pd2(N3)4Cl2], [(PNP)2][Pd(N3)4], [(AsPh4)2][Pt(N3)4] · 2 H2O und [(AsPh4)2][Pt(N3)6]

Die Kristallstrukturen der monomeren Palladium(II)-azid Komplexe des Typs L2Pd(N3)2 (L = PPh3 (1), AsPh3 (2) und 2-chloropyridin (3)), des dimeren [(AsPh4)2][Pd2(N3)4Cl2] (4), des homoleptischen Azido-Palladats [(PNP)2][Pd(N3)4] (5) und der homoleptischen Azido-Platinate [(AsPh4)2][Pt(N3)4] · 2 H2O (6) und [(AsPh4)2][Pt(N3)6] (7) wurden röntgenographisch an Einkristallen ermittelt. 1 und 2 sind isotyp und kristallisieren in der triklinen Raumgruppe P1. 1, 2 und 3 zeigen terminale Azidliganden, die trans zueinander angeordnet sind. Die [Pd2(N3)4Cl2]2– Anionen der Verbindung 4 zeigen sowohl end-on verbrückende Azid-Gruppen als auch terminale Chlor Atome und Azidliganden. Die Azidliganden der Anionen der Verbindungen 5 und 6 liegen auf gleichsinnigen Lagen mit annähernd lokaler C4h Symmetrie an den Platin- und Palladiumatomen. Die Metall-Atome weisen eine planare Umgebung auf. Die [Pt(N3)6]2–-Anionen in 7 sind zentrosymmetrisch (nahezu S6 Symmetrie), und die Platin-Atome sind von sechs Stickstoff-Atomen oktaedrisch umgeben.
