Abstract

The crystal structure of Ru(CO)(py)(TPP) has been determined from three-dimensional X-ray diffraction data. The compound crystallizes in the triclinic space group Ci1-P1 (a = 11.665 (1), b = 19.667 (2), c = 10.758 (2)Å; α = 92.22(1), β = 93.32(1), γ = 96.50(1)°; Z = 2), with three toluene molecules of crystallization. Leastsquares refinement has led to a final value of the conventional R factor (on F) of 0.065 for the 4617 reflections having Fo2 > 3σ(Fo2). The Ru(II) atom is 0.079 Å out of the porphyrin plane toward the carbonyl carbon atom. The Ru-C-O angle is 178.4 (7)° and the Ru-CO distance is 1.838 (9) Å. The Ru-N(pyridine) distance is 2.193 (4) Å, compared with the average Ru-N(porphyrin) distance of 2.052 (9) Å. The long axial Ru-N(py) bond length is attributed to a trans effect of the carbonyl group. The bond lengths and angles within the porphyrin compare well with those observed previously in Ru(CO)(EtOH)(TPP).
