Organo-substituted 1,3,5-hexahydrotriazine complexes of the type (RNCH2)3Mo(CO)3 (R = CH3, i - C3H7 and CH2C6H5) are obtained by ligand displacement from η6-C7H8Mo(CO)3 in high yields. These products have been characterized by 1H, 13C, 95Mo NMR, IR as well as mass spectroscopy and contain an electron-rich Mo(C O)3 center bonded to the 1,3,5-hexahydrotriazine 6e donor via three Mo -N bonds. Oxidation of the Mo0 complex 1,3,5-(CH3NCH2)3Mo(CO)3 with H2O2 under carefully controlled conditions allows isolation of 1,3,5-(CH3NCH2)3MoO3 containing a MoVI center. Chemical and spectroscopic properties of these complexes are compared with those of related Mo complexes with neutral macrocyclic ligands containing N3 donor sets.
