Abstract: | The reaction of MoBr3 and pyridine at room temperature provided single crystals of mer‐[MoX3Py3]. mer‐[MoBr3Py3] crystallizes in P21/n monoclinic space group with cell dimensions a = 9.2297(5) Å, b = 12.911(8) Å, c = 15.7022(9) Å 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) Å and Mo–Br distances are 2.573(1) Å and 2.574(1) Å. Fundamental vibrational frequencies of pyridine molecules are strongly affected upon coordination in all three coordination compounds: mer‐[MoBr3Py3], mer‐[MoI3Py3] and trans,trans‐[MoBr2Py4][MoBr4Py2]. |
