The compounds (a) (H3O)2[Mo6Cl8Cl6]·7H2O, (b) (H3O)2[Mo6Cl8Br6]·6H2O and (c) (H3O)2[Mo6Cl8I6]·6H2O were synthesized from MoCl2 and the corresponding halide acid. The structures were determined by X-ray diffraction and refined in the monoclinic space groups, (a) C2/c and for (b) and (c) P21/a. The cell parameters were for (a), a=17.3607(2), b=9.1351(7), c=18.6300(2) Å and β=98.13(1)°, (b) a=17.4295(2), b=9.3803(10), c=9.3769(12) Å and β=101.04(1)° and (c) a=18.0083(10), b=9.7612(10), c=9.8139(12) Å and β=100.20(2)°. The positions of the hydrogen atoms were determined by theoretical energy optimization. The structures are compared with respect to the effect of hydrogen bonding on the water structure.
