Tantalum chalcogenide halides

Although not yet published in a journal, according to thesis work, the vanadium compounds VSCl (11), VSBr, and VSI (208) seem to exist. Numerous niobium chalcogenide halides have been reported, and among these are the best characterized examples of Group VB (see Table X). Only two tantalum compounds, TaSjCU (361) and TaSCls (13) have thus far been described in the literature. 

The sulfido, seleno and telluro halides of the transition metals have been reviewed recently.540"542 Numerous Nb11 chalcogenide halides have been reported. For tantalum, only [Ta(S2)Cl2] and [Ta(S2)mCl ] (m = 1-3, n = 1-4), of unknown structure, obtained from TaCls and S8, have so far been reported.543...
