The reaction of MoO2(acac)2 with 2-amino-6-methyl-pyridine (amp) in the mixed solvent of DMF (N,N-dimethylformamide) and water affords the title complex [H-amp]4- [Mo8O26(DMF)2]2H2O which was characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction analysis with the following crystallographic data: C30H54Mo8N10O30, Mr = 1802.35, monoclinic, P21/n, a = 8.631(1), b = 24.260(3), c = 13.351(2) ? b = 104.688(3), V = 2704.2(7) 3, Z = 2, Dc = 2.213 g/cm3, m =1.890 mm-1 and F(000) = 1760. The final R = 0.0281 and wR = 0.0620 for 4935 observed reflections with I > 2s(I). X-ray structure analysis has confirmed the existence of g-[Mo8O26]4- anion in the molecule. Eight MoO6 distorted octahedra share edges with short terminal MoO bonds from 1.691(3) to 1.749(2) ? medium bonds from 1.868(2) to 1.965(2) ?and long bonds from 2.059(2) to 2.450(2) ? In the terminal site there exist two DMF ligands bound to the Mo atom through O atoms with the MoODMF bond length of 2.166(3) ? affording a bond strength of 0.433. A three-dimensional network structure was formed through hydrogen bonds.
