irradiation with hfb a 1 : 2 adduct. Replacement of co-ordinated CO in the adduct by P(OCH2)3CMe gave crystals of (9)[Ru(CO)2P(OCH2)3CMe}(C6H8)(C4F6)2] suitable for X-ray crystallography. Crystals of (9) are monoclinic, space group P21/c, with Z= 4 in a unit cell of drmensions: a= 8.875(5), b= 17.841 (9), c= 16.517(5)Å, β= 94.51(3)°.
