Synthesis of Complex Polymeric Telluridoindates from KInTe2
Four new polymeric telluridoindates [K(18-crown-6)][InTe2]center dot 2en (1) (18-crown-6 = 1,4,7,10,13,16-hexaoxacyclooctadecane), [K([2.2.2]crypt)](2)[In2Te6]center dot 0.5en (2) ([2.2.2]crypt = 4,7,13,16,21,24-H exaoxa-1,10-diazab icyclo[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 hg-topology in 4.
