Experimental and Theoretical Studies of Homoleptic Tellurium Cyanides Te(CN)x: Crystal Structure of Te(CN)2

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 & Co. KGaA, 69451 Weinheim, Germany, 2004)
