Structure cristalline du complexe [FeCp((-)DIOP)I] analyse conformationnelle du cycle de chelation de la (-)diop

The crystal structure of [FeCp((-)diop)I] has been determined by x-ray analysis and refined by least squares methods to R = 0.091 for 1603 independent reflections. The complex crystallises in the orthorhombic space group P212121 with a unit cell of dimensions a = 16.920 (3), b = 19.902(4), c = 10.649(6)». The conformation of the chelated (-)DIOP is analysed and compared with those occuridng in other complexes of known structures.
