Some compounds of the type (LH)2SnX6, (LH)2SbX5 (X Cl, Br), (LH)3Bi2X9 (X Cl, Br, I) and LHSbI4 (LH N-ethylmorpholinium cation) were prepared and characterized by means of the Raman and far i.r. spectroscopy.

Abstract
Some compounds of the type (LH)2SnX6, (LH)2SbX5 (X Cl, Br), (LH)3Bi2X9 (X Cl, Br, I) and LHSbI4 (LH N-ethylmorpholinium cation) were prepared and characterized by means of the Raman and far i.r. spectroscopy. The vibrational spectra are indicative of an octahedral configuration for the hexahalostannates(IV) and a square-pyramidal configuration for the pentahaloantimonates (III). The (LH)3Bi2X9 complexes may be interpreted on the basis of a D3h, symmetry. The hydrogen bonding ability of the counter cation seems to influence only the coordination geometry of the pentahaloantimonates (III).
