Abstract

The complex Co₂(CO)₆[μ-η²-(H₃CC{triple bond, long}CCH₂CH₂OH)] (1) with the ligand 3-pentyn-1-ol (pol) has been synthesized following established procedures. Its structure has been determined by X-ray analysis. The complex Co₂(CO)₆(mbo) (mbo = 2-methyl-3-butyn-2-ol, HC{triple bond, long}CC(CH₃)₂OH), (3), along with the already known Co₂(CO)₆(bud) (bud = 1,4-butyn-diol, HOCH₂C{triple bond, long}CCH₂OH) (2), and Co₂(CO)₈ were reacted with 2(diphenylphosphino)ethyl-triethoxysilane [Ph₂PCH₂CH₂Si(OCH₂CH₃)₃] (dpts) and tris(hydroxymethyl)phosphine [P(CH₂OH)₃] (thp). With dpts, mono- and di-substituted complexes were obtained: these were characterized by analytical and spectroscopic techniques. The structures of Co₂(CO)₆(dpts)₂ (5) and of Co₂(CO)₄(pol)(dpts)₂ (8) have been determined by X-ray analysis. Complex (1) was reacted with 3-(triethoxysilyl)propyl isocyanate [(H₃CCH₂O)₃Si(CH₂)₃NCO] (tsi): the new complex Co₂(CO)₆[H₃CC{triple bond, long}CCH₂CH₂OC({double bond, long}O)NH(CH₂)₃Si(OCH₂CH₃)₃] (9) was obtained and spectroscopically characterized. The complex has also been reacted with tetraethyl orthosilicate (teos); a new inorganic-organometallic material was obtained. Complex (5) has been grafted on the mesoporous material SBA-15. The hybrid inorganic-organometallic materials obtained have been characterized by inductively coupled plasma-mass spectrometry (ICP-MS), infrared spectroscopy (FT-IR) under vacuum conditions, X-ray diffraction (XRD) and scanning electron microscopy coupled to EDS probe (SEM-EDS).
