Copolymerisation of Pt–carbonyl clusters with Lewis acids: synthesis and crystal structure of the molecular {Cd 2 Cl 4 [Pt 9 (CO) 18 ] 2− } ∞ 1-D polymer

Reaction of [NBu4]2[Pt9(CO)18] with the soft Lewis acid CdCl2 gives the [Pt9(CO)18(micro3-CdCl2)2]2- adduct, which self-assembles upon crystallization into a 1-D [[Pt9(CO)18(micro3-CdCl2)2]2-]infinity polymer via the formation of chloride bridges.
