excited states. The complex Fe(CO)2(PEt3(bda) crystallises in the monoclinic space group P2l/c with a 10.203(3), b 12.964(4), c 16.960(6) Å, β 120.00(2)°, and Z = 4. The structure was solved by a combination of Patterson and Fourier diffence techniques and refined by blocked full matrix least squares to R = 0.035 for 3351 unique observed diffratometer data.
