  Europium Pyridinethiolates: Synthesis, Structure, and Thermolysis

  摘要：

  The transmetalation reaction of Hg(SPy)(2) (SPy = S-2-NC5H4) with Eu in pyridine gives the europium(II) pyridinethiolate coordination complex (py)(4)Eu(SPy)(2) (1) in 96% isolated yield. The reaction of 1 with BIPY in THF results in displacement of the pyridine ligands and the formation of the divalent coordination complex (BIPY)(TI-IF),Eu(SPy)2 (2). Low-temperature single-crystal X-ray diffraction experiments show that 1 and 2 are molecular 8 coordinate compounds. They are both intensely colored due to the presence of a visible europium-to-pyridine or europium-to-BTPY charge transfer (CT) absorption band. Trivalent [PEt(4)][Eu(SPy)(4)] (3) was prepared from the reaction of Eu/Hg amalgam with PySSPy in the presence of [PEt(4)][SPy]. X-ray diffraction analysis of 3 shows that all the pyridinechalcogenolate ligands are chelating the Eu(III) ion and there are three different eight coordinate isomers within the unit cell. Compound 3 is intensely colored because of a visible S-to-Eu CT absorption. At 500 degrees C, 3 decomposes to give EuS and a mixture of PySSPy, PySPy, EtSPy, and SPEt(3).
