Synthesis and characterization of bis(1,1,1,5,5,5,-hexafluoropentane-2,4-ionato) strontium and barium adducts with O- and N-ancillary ligands; crystal structure of Sr(HFAC)(2)center dot(BPY)(2)

摘要

Complexes of M(hfac)(2) . Ln [M = Sr, n = 1, L = retraglyme, db24c8; n = 2, L = bpy, phen; M = Ba, n = 1, L = tetraglyme, db24c8] have been prepared by in situ reactions of MX2 (X = OH, OAc) with Hhfac in the presence of the ancillary ligands in aqueous ethanol in high yields and characterized by H-1 NMR, IR, mass spectrometry and elemental analysis. A molecular structure of the complex Sr(hfac)(2) . (bpy)(2) has been determined by X-ray single crystal analysis. (C) 1997 Elsevier Science Ltd. [References: 22]
