[MoNCl 3 (THF)] 4 – a Nitrido Complex with a Folded Mo 4 N 4 Eight‐Membered Ring Red moisture sensitive single crystals of [MoNCl 3 (THF)] 4 ( 1 ) prepared from saturated solutions of CH 2 Cl 2 were characterized by a crystal structure determination. Space group P 4 2 1 c, Z = 2, lattice dimensions at –80 °C: a = b = 1291.2(1), c = 1116.3(1) pm, R = 0.0581. In 1 the molybdenum atoms are linked by nearly linear Mo≡N–Mo bridges with MoN distances of 167 and 216 pm, which corresponds with triple and single bonds. In trans position to the Mo≡N bond the THF molecule is bonded by its oxygen atom. Along the diagonal axis Mo…Mo 1 is folded with an aperture angle of 140° thus forming a butterfly structure.
