摘要：

Four new inorganic-organic hybrid polyoxomolybdates K-2[(SeMo6O21)-Mo-IV(L-O2CCHNH3 CH2OH)(3)]center dot 6H(2)O (1) and K-2[(SeMo6O21)-Mo-IV(D-O2CCHNH3CH2OH)(3)]center dot 6H(2)O (2), K-2[(TeMo6O21)-Mo-IV(D-O-2 CCHNH3CH2OH)(3)]center dot 6H(2)O (3) and K-2[(TeMo6O21)-Mo-IV(L-O2CCHNH3 CH2OH)(3)]center dot 6H(2)O (4) have been synthesized by a simple one -pot reaction of NaMoO4 center dot 2H(2)O, Na2SeO3/K2TeO3, KCl and corresponding chiral serine ligands in the aqueous medium and further characterized by single-crystal X-ray diffraction, elemental analyses, IR spectra, thermogravimetric (TG) analyses, electrospray ionization mass spectrometry (ESI-MS) and circular dichroism (CD) spectra. 1-4 are the representative chiral heteropolymolybdates featuring that a common {Se/TeMo6} fragment is made up of a six membered MoO6 octahedral ring functionalized by three serine ligands. TG analyses reveal that 1-4 undergo a two-step weight loss in the temperature range of 25-850 degrees C. (C) 2016 Elsevier B.V. All rights reserved.
