Vibrational and crystallographic studies of dioxohalogenomolybdenum(VI) complexes with crown ethers

Abstract

Crown ether adducts [MoO2X2(H2O)2]·2H2O·18-crown-6 (X = Br 1 or Cl 2), obtained by combining solutions of MoVI in HBr or HCl with 1,4,7,10,13,16-hexaoxacyclooctadecane (18-crown-6), were shown by X-ray crystallography to contain MoO2X2(H2O)2 units with cis,trans,cis ligand arrangement. Recrystallisation from methyl alcohol yielded [MoO2Cl2(MeOH)2]·18-crown-6 3 which was also characterised by X-ray analysis. Adding potassium ions to the HCl system gave [K(18-crown-6)][MoO2Cl3(H2O)] 4 which was identified by studying Raman and IR spectra of the series.
