tricarbonylnickel complex 8 and the tetracarbonyliron derivative 10. The dimanganese compound 7 was found to be diaxially substituted with short MnC bonds but standard MnP bond lengths. The nickel compound 8 exhibited short PNi bonds, long NiC bonds and short CO bonds, consistent with enhanced π-back donation from metal to phosphorus. The coordination geometry at the iron atom in 10 was found to be trigonal bipyramidal

phosphorus compounds was found to increase in the order 5 < 2 < 19 < 13 HTMG < 21; the basic centre is the phosphorus atom in 21 and the imino nitrogen atom in all other compounds. The fluorinatingagent Et3N · 3 HF caused rapid conversion of compound 6to 25, the nucleophilic attack of fluoride ion at phosphorus could not be prevented by the stabilizing effects mentioned. – All compounds were investigated
