摘要：
Complexes of L-2 thiolhistidine (th) and 2-mercaptoimidazole (miz)with Pd(II) were synthesized; Pd(th)(4)(NO3)(2) and Pd(miz)(4)Cl-2, and their structure determined by FTIR, UV/VIS, NMR, mass spectroscopy, and X-ray crystallography. For comparison, a Pd(II) complex with thiourea (tu), Pd(tu)(4)Cl-2, was prepared. This compound has been reported in the literature. Spectral evidence indicates a single coordination site between the Pd(II) and S for all complexes. A Pd-S stretch band was identified for all complexes. NMR spectra provided evidence for deshielding effects in the; complexes from that of its ligands. Charge transfer bands were identified in the UV!VIS spectra for the new complexes as well. The crystal structure for Pd(miz)(4)Cl-2 was determined. Unit cell data was found to be: a = 8.102(3)Angstrom, b = 8.300(3)Angstrom, c = 8.304(3)Angstrom. The crystal system is triclinic and the space group is P $$($) over bar 1.
