N2 - Bismuth halides BiX3 (X = Cl, Br) react readily with two equivalents of Na+ CpFe(CO)2- to give the μ-halobismuthane complexes [CpFe-(CO)2]2BiX, which react further with triethylaluminium to give the μ-ethylbismuthane [CpFe(CO)2]2BiEt. Treatment of BiCl3 with three equivalents of Na+ CpFe(CO)2- gives the open cluster compound [CpFe(CO)2]3Bi, which undergoes photochemical decarbonylation to the closo tetrahedral cluster [CpFe(μ2-CO)]3Bi. The trimeric nature of solid {[CpFe(CO)2]2BiCl}3 has been shown by single crystal X-ray diffraction. The chlorine atoms provide three bridges between the Bi atoms, forming a six-membered ring, with three CpFe(CO)2 units above and three below the planar Bi3Cl3 ring. (Crystals are monoclinic, C2/c with a 12.296(1), b 21.398(2), c 37.672(5) Å, β 90.07(1)°, V 9911.9 Å3, Dc 2.406 g cm-3 for Z = 8, Rw = 0.038 for 592 refined parameters and 5464 observables).
