  名称：

  Metal complexes of 2-aza-2-benzyl-5,10,15,20-tetraphenyl-21-carbaporphyrin: M(2-NCH2C6H5NCTPP) (M=Ni2+, Pd2+) and Mn(2-NCH2C6H5NCTPP)Br (NCTPP=N-confused 5,10,15,20-tetraphenyl porphyrinate)

  摘要：

  The crystal structures of (2-aza-2-benzyl-5,10,15,20-tetraphenyl-21-carbaporphyrinato-N,N',N '') nickel( II) methylene chloride solvate [Ni(2-NCH2C6H5NCTPP); 4], (2-aza-2-benzyl-5,10,15,20-tetraphenyl-21-carbaporphyrinato-N,N',N '') palladium(II) [Pd(2-NCH2C6H5NCTPP); 5] and bromo(2-aza-2-benzyl-5,10,15,20-tetraphenyl-21-carbaporphyrinato-N,N',N '') manganese(III) toluene solvate [Mn(2-NCH2C6H5NCTPP) Br center dot C6H5CH3; 3 center dot C6H5CH3] have been established. The coordination sphere around the Ni2+ ion in 4 (or Pd2+ ion in 5) is distorted square planar (DSP), whereas for Mn3+ in 3 center dot C6H5CH3, it is a square-based pyramid with the Br atom lying in the axial site. The g value of 11.34, measured from parallel polarization of the X-band EPR spectra at 4K, is consistent with a high spin mononuclear manganese(III) centre (S = 2) in 3. The magnitude of the axial (D) zero-field splitting (ZFS) for the mononuclear Mn(III) centre in 3 was determined approximately to be 1.4 cm(-1) by paramagnetic susceptibility measurements and conventional EPR spectroscopy.
