2. Hydroboration of (mu-H)2Os3(CO)10: formation of the borylidyne cluster (mu-H)2Os3(mu-H)2BH. An improved synthesis of (mu-H)3Os3(CO)9(mu3-BCO)

Abstract

The formation of a new borylidyne cluster from the reaction of (mu-H)2Os3(CO)10 and BH3S(CH3)2 was described. Nuclear magnetic resonance spectroscopy results were similar to the spectra results of iron and ruthenium borylidyne clusters. Bond angles and distances between the osmium and carbon showed the presence of bridging hydrogen atoms. The two types of structures described reflect the role of the transition metal in the position of the bridging hydrogens.

3. Coordination geometries of solvated lanthanide(II) ions: molecular structures of the cationic species ((DIME)3Ln)2+ (DIME = diethylene glycol dimethyl ether; Ln2+ = Sm, Yb), ((DIME)2Yb(CH3CN)2)2+, ((DIME)Yb(CH3CN)5)2+, and ((C5H5N)5Yb(CH3CN)2)2+

Abstract

Divalent lanthanide cationic species, which are used as molecular precursors for bimetallic films and metal borides and have coordination numbers seven, eight and nine, were synthesized and structurally characterized. Divalent lanthanides such as Sm(II), Yb(II) and Eu(II) behave as precursors when all other ligands are neutral and easily removable. Divalent lanthanides were studied with hydroborate and transition metal carbonylate substrates.

Abstract

The ethylidyne cluster (mu-H)3Os3(CO)9(mu3-CCH3) was synthesized by the addition of excess BH3.THF in CH2Cl2 to (mu-H)2Os3(CO)9(mu3-CCO) which involved the reduction of the unique carbonyl to a methyl group. The presence of ethylidine was also confirmed by X-ray crystal structure determination. The molecular structure of the cluster was described to be of triosmium symmetry made up of an Os3 triangle with three bounded carbonyls per Os atom. The observation was parallel with the result from an X-ray powder diffraction analysis.

Abstract

A simple, economic chemical vapor deposition (CVD) method for the coating of substrates with high quality homogeneous thin metal films has been developed. The physical and magnetic properties of these magnetic films have been evaluated and the results show that the film quality achieved is equivalent to those made by other techniques.
