The coordination compounds of silver(I) halides or nitrate with tetramethylthiuram monosulfide (Me4TMS) have been prepared. Their IR and Raman Spectra show that the halide derivatives possess a dimeric halogen-bridged structure (Ia) of D2h symmetry, whereas the nitrate complex contains a bidentate ...
