Abstract
  • The monoglyme [CH3OCH2CH2OCH3] and diglyme [CH3O(CH2CH2O)(2)CH3] adducts of the neodymium tris-hexauoroacetylacetonato [Nd(hfa)(3)center dot monoglyme center dot H2O and Nd(hfa)(3)center dot diglyme] have been synthesised in a single step reaction. They have been characterized by elemental analyzes, mass spectrometry, and IR spectroscopy. Single crystal X-ray diffraction studies provide evidence of a mononuclear nine-coordinated complex with a monocapped square antiprismatic structure for the Nd(hfa)(3)center dot diglyme (monoclinic system, space group P2(1)/n; a = 9.7717(2), b = 15.5723(4), c = 20.5620(5)angstrom, beta = 103.668(2)degrees; Z = 4). The Nd(hfa)(3)center dot monoglyme center dot H2O consists of asymmetric units containing two similar molecules (monoclinic system, space group = C2; a = 16.7057(4), b = 12.2579(4), c = 29.3734(5)angstrom, beta = 101.170(3)degrees, Z = 8). The mass transport properties of these adducts have been investigated by thermogravimetric analysis which revealed high volatility and good thermal stability with a residue left lower than 3%. The Nd(hfa)(3)center dot diglyme has been successfully applied to the low-pressure metal organic chemical vapor deposition (MOCVD) of NdBa2Cu3O7 (delta) thin films. (literal)
