A new fullerene co-crystal C60SiH(C6H5)3has been synthesized by crystallisation from a melt of SiH(C6H5)3and C60in sealed duran tubes at 80C. X-ray investigations led to triclinic symmetry, space group P¯1, a = 10.086(1), b = 14.431(2), c = 14.911(2) ˚A, = 79.13(1),

= 74.943(9),= 88.33(1), V = 2058.0(4) ˚A3, Z = 2. The crystal structure consists of isolated fullerene and silane molecules. At –80C, C60 is still rotationally disordered. Temperature dependent Guinier powder diagrams do not show any phase transformation between 25 and –165C. The compound is stable in air.
