摘要：

Trans,trans-[MoX(2)py(4)][MoX(4)py(2)] (X = Cl, A; Br, B; py = pyridine, C5H5N) are the side products of reaction of between (NH4)(2)[MoX(5) . H5O] (X = Cl, Br) with pyridine diluted with methanol. Both trans,trans-[MoX(2)py(4)][MoX(4)py(2)] are monoclinic, P2(1)/n space group, with z = 2 and: a = 12.568(1), b = 9.430(1), c = 14.952(1) Angstrom and beta = 100.81(1)degrees (A); a = 12.551(2), b = 9.533(2), c = 15.366(2) (Angstrom) and beta = 99.35(1) (B). Cations and anions are located on the symmetry centers and have eclipsed conformation of the trans located pyridine ligands. Average Mo-X and Mo-N (pyridine) bonds are: (cation) 2.41, 2.21 Angstrom (A); 2.54, 2.21 Angstrom (B); (anion) 2.44, 2.20 Angstrom (A); 2.58, 2.20 Angstrom (B). Anionic part of the compounds can be oxidised by bromine to trans-MoX(4)py(2), which precipitates from the solution. Cation can be isolated from the solution in the form of trans[MoX(2)py(4)]Br-3 (X = Cl, Br). The compounds were also characterised by chemical analysis, infrared spectroscopy and conductivity measurements.
