NiII, PdII Complexes with Pyrene‐based Thiosemicarbazones: Syntheses, Molecular Structures, and Excimeric Emissions

A series of NiII and PdII complexes with pyrene‐based thiosemicarbazones were conveniently prepared. The crystal structures of Ni(L2)2, Pd(L1)2, and Pd(L2)2 were determined. X‐ray crystallographic analysis reveals that the complexes are of mononuclear structure with two pyrenyl rings cofacially alig...

Description
Summary:A series of NiII and PdII complexes with pyrene‐based thiosemicarbazones were conveniently prepared. The crystal structures of Ni(L2)2, Pd(L1)2, and Pd(L2)2 were determined. X‐ray crystallographic analysis reveals that the complexes are of mononuclear structure with two pyrenyl rings cofacially aligned. The photoluminescence spectra of the complexes exhibit moderate characteristic excimeric emissions arising from intramolecular π–π stacking between pyrenyl rings.
