Triazapentadienides, C(3)F(7)-C(=NR)-N=C(NHR)-C(3)F(7), result from the reaction of primary amines RNH(2) with fluorinated imine C(3)F(7)-CF=N-C(4)F(9). The aniline derivative (R = Ph) is a weak monoprotic acid in dmso. Its conjugate base exhibits an extensive coordination chemistry. It acts as bidentate ligand toward molecular fragments Pd(C(3)H(5)), Rh(c-C(8)H(12)), Ir(c-C(8)H(12)), and Rh(CO)(2). chelates [C(3)F(7)-C(NPh)-N-C(NPh)-C(3)F(7)](2)M, M Mg, Mn, Fe, Co, Ni, Cu, Zn, Pd, were prepared. In crystallographically characterized Co complex, metal 3d(7), S (3)/(2) tetrahedrally coordinated. Spin densities at carbon C(6)H(5) C(3)F(7) groups estimated (1)H (19)F contact shifts. delocalization onto phenyl sp(2) carbons approximately 10 times greater than sp(3) carbons.
