Abstract

The complexes [Mo{HB(3,5-Me2C3HN2)3}(NO)I(Y)](Y = NMe2 or NHR, where R = H, Me, Et, Prn, Pri, Bun, Bui, C6H11, C3H5, or CH2Ph) and [W{HB(3,5-Me2C3HN2)2(4-Br-3,5-Me2C3N2)})(NO)Br(Y)](Y = H, Pri, or CH2Ph) have been prepared by treatment of the species where Y = I (MO) or Br (W) with ammonia, primary amines, and NHMe2 respectively. Reaction of [Mo{HB(3,5-Me2C3HN2)3}(NO)I(NH2)] with HCl, and with acetone in the presence of NEt3 respectively, gives [Mo{HB(3,5-Me2C3HN2)3}(NO)Cl2] and [NH4]Cl, and [Mo{HB(3,5-Me2C3HN2)3}(NO)I(N[double bond, length half m-dash]CMe2)]·Me2CO. The crystal and molecular structure of [Mo{HB(3,5-Me2C3HN2)3}(NO)I(NHEt)], as a di-isopropyl ether solvate, has been determined by X-ray diffraction methods using counter data and refined by block-diagonal least-squares procedures, to R= 0.0534 for 3 150 reflections. The molecule is six-co-ordinate, with a linear Mo–N–O group, and a short Mo–NHEt bond. Crystals are monoclinic with a= 40.00(3), b= 12.751 (10), c= 10.60(3)Å, β= 97.23(2)°, space group P21/a, and Z= 8.
