The crystal structures of the monomeric palladium(II) azide complexes of the type L 2 Pd(N 3 ) 2 (L = PPh 3 ( 1 ), AsPh 3 ( 2 ), and 2‐chloropyridine ( 3 )), the dimeric [(AsPh 4 ) 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 [(AsPh 4 ) 2 ][Pt(N 3 ) 4 ] · 2 H 2 O ( 6 ) and [(AsPh 4 ) 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 P 1. 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.
