Dodecamethylcyclotetrasilazane (I) was prepared for the first time according to scheme 1 [eqns. (2)–(5)] and confirmed in its structure by NMR and IR spectroscopy. It melts at 258-260° but transforms at 51-52° into plastic crystals. ...
An analysis of the infrared spectra, in the 1200–900 cm 1 region, of compounds of the type R 2 MCH 2CHR′CHR″O or R 2 MCH CHCR′R″O (R 2M = Me 2Si, Et 2Ge or n-Bu 2Sn; R′ = R″ = H or Me), allows us to distinguish between monomers, coordination dimers, true ...
The crystal and molecular structure of trichlorogermylcobalt tetracarbonyl. Cl3GeCo(CO)4, has been determined from three-dimensional X-ray data collected by counter methods. The structure has been resolved by vector-analysis and refined by least-squares techniques. It crystallizes in spacegroup Cc...
