The compound Bi(TeSi t Bu 2 Ph) 3 ( 1 ) was obtained from the reaction of BiCl 3 with t Bu 2 PhSiTeSiMe 3 in diethyl ether. The single crystal structure analysis revealed a trigonal pyramidal structure of the BiTe 3 core and weak Bi···C (arene) contacts. Compound 1 was characterized by multinuclear NMR spectroscopy, IR spectroscopy and elemental analysis. Thermogravimetric experiments show that compound 1 decomposes with formation of Bi 2 Te 3 or a mixture of elemental bismuth and Bi 4 Te 3 , depending on the pressure conditions.
