Crystal structures of (PPh3)(2)Pd(N-3)(2), (AsPh3)(2)Pd(N-3)(2), (2-chloropyridine)(2)Pd(N-3)(2), [(AsPh4)(2)][Pd-2(N-3)(4)Cl-2], [(PNP)(2)][Pd(N-3)(4)], [(AsPh4)(2)][Pt(N-3)(4)]center dot 2H(2)O, and [(AsPh4)(2)][Pt(N-3)(6)]

The crystal structures of the monomeric palladium(II) azide complexes of th e type L2Pd(N-3)(2) (L = PPh3 (1), AsPh3 (2), and 2-chloropyridine (3)), th e dimeric [(AsPh4)(2)][Pd-2(N-3)(4)Cl-2] (4), the homoleptic azido palladat e [(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 crystall ize 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 brid ging 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 at oms show a planar surrounding. The [Pt(N-3)(6)](2-) anions in 7 are centros ymmetric (idealized S-6 symmetry) with an octahedral surrounding of six nit rogen atoms at the platinum centers.
