Title: Synthesis, structural and spectroscopic characterization of new polychalcogenide complexes of indium and thallium, and their application as precursors to solid state materials. (Volumes I and II)

Abstract

To study the coordination chemistry of group III-A metals with polychalcogenide ligands, the authors undertook a systematic investigation of this system and were able to isolate a number of structurally interesting indium and thallium polychalcogenides complexes. The polyselenide complexes exhibit the structural diversity in this system (Ph[sub 4]P)[sub 4] [In[sub 2](Se[sub 4])[sub 4](Se[sub 5])], (Pr[sub 4]N)[sub 4] [In[sub 2](Se[sub 4])[sub 4](Se[sub 5])], (Et[sub 4]N)[sub 4][In[sub 2](Se[sub 4])[sub 4](Se[sub 5])], (Pr[sub 4]N)[sub 2][In[sub 2]Se[sub 2](Se[sub 4])[sub 2]], [(Ph[sub 3]P)[sub 2]N][sub 2][In[sub 2]Se[sub 2](Se[sub 4])[sub 2]], (Et[sub 4]N)[sub 3][In[sub 3]Se[sub 3](Se[sub 4])[sub 3]], (Et[sub 4]N)[sub 3][Tl[sub 3]Se[sub 3]S(Se[sub 4])[sub 3]] and (Et[sub 4]N)[sub 5][NaIn[sub 6]Se[sub 6] (Se[sub 4])[sub 6]]. Similar structural diversity is also seen in the polysulfide complexes: (Ph[sub 4]P)[sub 2][In(S[sub 4])(S[sub 6])X] (X = Br, Cl) (Ph[sub 4]P)[sub 4][In[sub 2](S[sub 4])[sub 2](S[sub 6])[sub 2](S[sub 7])], (Ph[sub 4]P)[sub 2][In[sub 2]S(S[sub 5])(S[sub 4])[sub 1.5](S[sub 6])[sub 0.5]]; [alpha]-(Ph[sub 4]P)[sub 2][Tl[sub 2](S[sub 4])[sub 2]](S[sub 4])[sub 2], [beta]-(Ph[sub 4]P)[sub 2][Tl[sub 2](S[sub 4])[sub 2]][center dot]2DMF, [beta]-(Ph[sub 4]P)[sub 2](S[sub 4])[sub 2]].2DMF, [gamma]-(Ph[sub 4]P)[sub 2][T[sub 2](S[sub 4])[sub 2].DMF, (Et[sub 4]N)[sub 2][Tl[sub 2](S[sub 4])[sub 2]], (Me[sub 4]N)[sub 2][Tl[sub 2](S[sub 4])[sub 2]] and K[sub 0.68]Tl[sub 1.32]S[sub 5]. The compounds (Ph[sub 4]P)][Ga(Se[sub 6])[sub 2]], (Ph[sub 4]P)[In(Se[sub 6])[sub 2] and (Ph[sub 4]P)[Tl(Se[submore » 6])[sub 2]], exhibit an unusual and open layered framework. The synthetic strategies, X-ray crystal structures and physicochemical properties of these new polychalcogenide complexes are illustrated. These complexes are excellent low temperature precursors for films of binary and ternary solid state compounds which are obtained as single phases.« less
