Abstract
The phosphoraneiminato complexes [MnBr(NPEt3)](4) 3, [FeCl(NPEt3)](4) 4 and [CoBr(NPEt3)](4) 5 were built from the element halides MX, and e xcess trimethylsilyltriethylphosphoraneimine in the presence of potass ium fluoride. They form shiny orange (M = Mn), dark brown (M = Fe), an d dark green (M = Co) crystals. According to single crystal structure determinations these compounds form M4N4 heterocubane frameworks with mu(3)-N-bridges and M-N bond lengths of 213.4 pm (M = Mn), 205.7 pm (M = Fe), and 204.4 pm (M = Co) which lead to intermetallic distances of 295.7 pm (M = Mn), 272.9 pm (M = Fe), and 279.0 pm (M = Co).
