Abstract

The reaction of [Os3(CO)10(MeCN)2] with 2-phenylazopyridine (2-PAP) affords [Os3(CO)10(NC5H4NNC6H5)] (1), [Os3(CO)10(μ-H)(NC5H3NN(O)C6H5)] (2) and a violet product 3, which is an isomer of 1. In 1, the 2-PAP moiety acts as the rarely observed six-electron donor. Cluster 2 contains an 'oxidized' 2-PAP moiety bonding in the usual ortho-metallated mode of pyridine. Both clusters 1 and 2 have been fully characterized in solution by conventional spectroscopic methods and in the solid state by single crystal X-ray diffraction analysis. Crystals of 1 are orthorhombic, space group P212121, Z = 4, with unit cell dimensions a = 9.123(1), b = 17.217(2), c = 16.168(2) A ̊. Crystals of 2 are triclinic, space group P1, Z = 2, with unit cell dimensions a = 9.308(2), b = 11.250(2), c = 12.934(2) A ̊, α = 77.23(1), β=72.26(1), γ=85.21(1)°.
