The complexes Na2[MoO2(S-Hmal)2]·4H2O (1) and K2[MoO2(S- Hmal)2]·2H2O 2 were prepared from the reaction of S-malic acid and molybdate. The two complexes were characterized by elemental analysis, conductivity measurement, optical rotation and IR measurement. 1 was characterized by NMR and X-ray diffraction method. It crystallizes in orthorhombic space group P 212121 with unit cell parameters: a=2.1000 (1), b=1.07569 (8), c=0.79356 (6) nm, V=1.7926 (4)nm3, Z=4,Dc=1.890g.cm-3, F(000)=1024, m=8.355cm-1, R=0.0309 and Rw=0.0366 for 1900 reflections with I≥3s (I). The molybdenum atom is coordinated by two bidentate S-malato ligands through a-alkoxy and a-carboxy group. The polymeric coordinated anion is connected by strong hydrogen bonding. The absolute configuration of the coordinated anion is D-S,S.
