Abstract

The reaction of Fe2(CO)6(μ-Se2) with ButC≡P in THF solvent, in the presence of sodium hydride, yields the tetrairon cluster Fe4Se2(μ-Se2PCBut)(CO)11. It has been characterized by IR and 1H, 31P, and 77Se NMR spectroscopy, and its molecular structure has been established by single-crystal X-ray diffraction methods. The structure can be described as consisting of a bow-tie type Fe3Se2 unit, one face of which is capped by an unusual FeSe2P unit, in which one Se is 3-coordinate and the other 2-coordinate. The second face is capped by a P-C(CH3) group such that the P atom is bonded to the middle Fe atom of the Fe3Se2 bow tie and the C atom is attached to one Fe atom and one Se atom. Nonlinear optical properties of Fe4Se2(μ-Se2PCBut)(CO)11, measured by the Z-scan technique, indicate significant magnitudes for the third-order susceptibility.
