Abstract: | The crystal and molecular structure of pyridinium di- -oxo-bis(oxodichloroaquomolybdate(V)) monohydrate has been determined from MoK diffractometer data. The compound crystallizes in the monoclinic space groupP2
1/m witha = 7.544(1),b= 17.046(3),c = 7.894(1) Å, = 106.00(1) ° andZ = 2. The structure was solved by the heavy-atom technique and refined by full-matrix least-squares method toR = 0.046, using 1800 reflections for whichF> 4 (F). Molybdenum atoms are linked by the double oxygen bridge with an Mo—O distance of 1.943(4) Å and an Mo—O—Mo angle of 83.4(2) °. The Mo—Mo distance is 2.584(1) Å, indicating direct Mo—Mo bonding. The pyridinium and Mo2O4C14(H2O)2]2- ions are hydrogen bonded through N—H ... O bonds. The N ... O contact is 2.656(8) Å. |
