Darstellung,spektroskopische und röntgenographische Untersuchung von monomerem Sb(CCCH3)5 und dimerem Sb(OCH3)5

Preparation, Spectroscopic and X-Ray Structure Investigations of Monomeric Sb (CCCH₃)₅ and Dimeric Sb (OCH₃)₅ Prop₃SbCl₂ (Prop ? C?C? CH₃) reacts with NaProp to form SbProp₅. This compound is monomeric in solution and in solid state and has according to the vibrational spectra a trigonal-bipyramidal structure of D_3h symmetry. The X-Ray structure determination shows the monoclinic space group C2/c with 8 formula units per cell. Dimeric Sb(OMe)₅ (Me ? CH₃) is formed by the interaction of SbProp₅ with MeOH in an 1:5 molar ratio. The structure is determined by ¹H, ¹³C-NMR, IR and Raman spectra and the crystal structure of this alkoxide is described.
