The complexes (NO)I(Y)> (Y=NMe2 or NHR, where R=H, Me, Et, nPr, iPr, nBu, tBu, C6H11, C3H5, or CH2Ph) and (NO)Br(Y)> (Y=H, iPr, 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 HB(3,5-Me2C3HN2)3>(NO)I(NH2)> with HCl, and with acetone in the presence of NEt3 respectively, gives (NO)Cl2> and Cl, and (NO)I(N=CMe2)>*Me2CO.The crystal and molecular structure of (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 3150 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) angstroem.β=97.23(2) deg, space group P21/a, and Z=8.
