【 摘 要 】

The complexes Pd(nbmtp)Cl2 and Pt(nbmtp)Cl2 (nbmptp = 1-nonyl-3,4-bis(methylthio)pyrrole) were prepared and their x-ray structures were determined at room temperature. The four-coordinated metal unit and the pyrrole ring formed a nearly planar geometry. The free ligand dissolved in CH₂Cl₂ produced two luminescence bands associated with the lone-pair electron of S (�?_max = 525 nm) and the pyrrole �? electron (�?_max = 388 nm). When the two complexes were dissolved in CH2Cl2, these two luminescence bands were also observed, although the low-energy band was blueshifted. For the crystalline Pt(II) complex, only the strong charge transfer band (�?_max = 618 nm) from the d* orbital of Pt resulted from excitation of the lone-pair electron of S.
