Abstract

The dinitrile (L), which includes two thioethereal sulfurs in the bridging group, has been synthesized in three reaction steps from 4-tert-butylthiophenol with an overall yield of 4.3%. The reaction of silver(I) hexafluorophosphate with L leads to the silver(I) complex, AgL2PF6, while the copper(I) complex, CuL2BF4, is prepared by a ligand exchange reaction. By the usage of the molar conductances and mass spectra, tetrafluoroborate in CuL2BF4 and hexafluorophosphate in AgL2PF6are ionized. Judging from the IR and NMR spectra, the C≡N group in the complexes serves as a σ-donor and the thioethereal sulfurs in the bridging group are not coordinated to the metal atoms.
