摘要

The reaction of MoBr_3 and pyridine at room temperature provided single crystals of mer-[MoX_3Py_3]. mer-[MoBr _3Py_3] crystallizes in P2_1 monoclinic space group with cell dimensions a = 9.2297(5) ?, b = 12.911(8) ?, c = 15.7022(9) ? and β = 90.479(3)°. There are four formula units in a unit cell. Mo-N distances are in the range 2.196(8)-2.214(8) ? and Mo-Br distances are 2.573(1) ? and 2.574(1) ?. Fundamental vibrational frequencies of pyridine molecules are strongly affected upon coordination in all three coordination compounds: mer-[MoBr_3Py_3], mer-[MoI_3Py_3] and trans,trans-[MoBr_2Py _4][MoBr_4Py_2].

Mo-Br距离为2.573(1)?和2.574(1)?。吡啶分子的基本振动频率在所有三种配位化合物中均受配位强烈影响:mer- [MoBr_3Py_3],mer- [MoI_3Py_3]和trans,trans- [MoBr_2Py _4] [MoBr_4Py_2]。
