Comparing structures and reactivity in analogous Fe and Ru complexes. (iPr-DAB)Fe(CO)2I2 and (iPr-DAB)FeI2: A perfectly reversible CO-carrier system. (R-DAB=N,N′-R2-1,4-diaza-1,3-butadiene)

Fe(iPr-DAB)(CO)3 (1a) oxidatively adds I2 to give (iPr-DAB)Fe(CO)2-trans-I2 (2a). Photochemically or thermally, 2a readily dissociates both carbonyl ligands to give tetrahedral Fe(iPr-DAB)I2 (3a). Under an atmosphere of CO, complex 2a is quantitatively regenerated from 3a. The X-ray crystal structures of 2a and 3a have been determined. 2a: triclinic, space group P1?, a=8.7624(3), b=9.0550(4), c=10.6512(6) ?, α=95.429(4), β=105.245(4), γ=95.209(3)°, Z=2, R=0.0251. 3a: orthorhombic, space group Aba2, a=11.2693(10), b=15.933(2), c=7.5958(10) ?, Z=4, R=0.036. Contrasting the behaviour of 2a, the analogous ruthenium complexes (R-DAB)Ru(CO)2trans-I2 (4) are very stable, and the carbonyl ligands cannot be dissociated thermally. In the dichloro complexes, of which both the kinetic trans- (5) and the thermodynamic cis-compounds (6) have been isolated, both isomers undergo a photochemical CO mono-substitution to give for example the isolable trans-dichloro methanol complex (7).
