Synthesis of Complex Polymeric Telluridoindates from KInTe2

Four new polymeric telluridoindates [K­(18-crown-6)]­[InTe2]·2en (1) (18-crown-6 = 1,4,7,10,13,16-hexaoxacyclooctadecane), [K([2.2.2]­crypt)]2[In2Te6]·0.5en (2) ([2.2.2]­crypt = 4,7,13,16,21,24-Hexaoxa-1,10-diazabicyclo[8.8.8]­hexacosane), [HTMDP]2[In4Te8] (3) (TMDP = 4,4′-trimethylenedipiperidine), and [HDAP]8[In12Te23] (4) (DAP = 1,3-diaminopropane) were prepared from KInTe2 as a starting material. With [InTe4] tetrahedra as the primary building unit in all four compounds, there is a significant increase in complexity in going from the simple chain-like anionic structures in 1 and 2 to an intricate band-type anion in 3 and finally an anionic framework with lig-topology in 4.
