Crystal structures of (PPh3)2Pd(N3)2, (AsPh3)2Pd(N3)2, (2-chloropyridine)2Pd(N3)2, [(AsPh4)2][Pd2(N3)4Cl2], [(PNP)2][Pd(N3)4], [(AsPh4)2][Pt(N3)4]•2H2O, and [(AsPh4)2][Pt(N3)6]

The crystal structures of the monomeric palladium(II) azide complexes of the type L2Pd(N-3)(2) (L = PPh3 (1), AsPh3 (2), and 2-chloropyridine (3)), the dimeric [(AsPh4)(2)][Pd-2(N-3)(4)Cl-2] (4), the homoleptic azido palladate [(PNP)(2)][Pd(N-3)(4)] (5) and the homoleptic azido platinates [(AsPh4)(2)][Pt(N-3)(4)]. 2H(2)O (6) and [(AsPh4)(2)][Pt(N-3)(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 [Pd-2(N-3)(4)Cl-2](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 C-4h symmetry at the platinum and palladium atom respectively. The metal atoms show a planar surrounding. The [Pt(N-3)(6)](2-) anions in 7 are centrosymmetric (idealized S-6 symmetry) with an octahedral surrounding of six nitrogen atoms at the platinum centers.
