By the reaction of triorganylcyclotriphosphines with transition metal complexes single-and polynuclear compounds are formed, in which the cyclophosphines are bonded in different ways to the metal, the ring either preserving structure or under going ring opening. Depending on the reaction conditions the following compounds can be characterized: [(PPh3)2Pt(PtBu)3] (1), [(PPh3)2Pd(PtBu)2] (2), [(CO)4Cr{(PiPr)3}2] (3), [RhCl(PPh3)(PtBu)3] (4), [(NiCO)6(μ2-CO)3{PtBu) 2}2] (5) and [(CPFeCO)2(μ-CO)(μ-PHtBu)]+ · [FeCl3(thf)]- (6). The structures of 1-6 were obtained by X-ray single crystal structure analysis (1: space group P21/n (No. 14), Z = 4, a = 1279.6(3) pm, b = 1733.1(4) pm, c = 2079.1(4) pm, β = 90.20(3)°; 2: space group P21/c (No. 14), Z = 4, a = 1053.3(2) pm, b = 2085.2(4) pm, c = 1855.7(4) pm, β = 98.77(3)°; 3: space group P1 (No. 2), Z = 2, a = 1022.6(2) pm, b = 1026.4(2) pm, c = 1706.0(3) pm, α = 82.36(3)°, β = 86.10(3)°, γ = 64.40(3)°; 4: space group P1 (No. 2), Z = 2, a = 980.2(2) pm, b = 1309.5(3) pm, c = 1573.4(3) pm, α = 99.09(3)°, β = 99.46(3)°, γ = 111.87(3)°; 5: space group P21/c (No. 14), Z = 4, a = 1804.0(5) pm, b = 2261.2(6) pm, c = 1830.1(7)pm, β = 96.99(3)°; 6: space group P21/c (Mo. 14), Z = 4, a = 943.2(3) pm, b = 2510.6(7) pm, c = 1325.1(6) pm, β = 98.21(3)°).
