Experimental and Theoretical Studies of Homoleptic Tellurium Cyanides Te(CN)_<i>x</i>: Crystal Structure of Te(CN)₂

Abstract

Abstract The labile tellurium cyanide species Te(CN) 2 and Te(CN) 4 have been prepared by treatment of tellurium( IV ) tetrahalides with cyanide. Both are thermosensitive solids and, in addition, the tetracyanide was found to be pyrophoric. The crystal structure of Te(CN) 2 has been determined. The structures of Te(CN) 2 , Te(CN) 4 , and Te(CN) 6 have been calculated at various levels of theory. (© Wiley‐VCH Verlag GmbH &amp; Co. KGaA, 69451 Weinheim, Germany, 2004)
