Crystal growth of metal tellurides and tellurometalates employing solvothermal reactions at temperatures below 200°C have resulted in four new indium tellurium phases, [Fe(en)3](In2Te6) (I), [Zn(en)3](In2Te6) (II), and α-and β-[Mo3(en)32-Te2) 33-Te)(μ3-O)]In2Te 6 (III-α and III-β). Single crystal X-ray diffraction analyses show that I and II are isostructural and belong to the orthorhombic crystal system, space group P212121 (No. 19). Compound I: a = 11.654 (1) Å, b = 12.968(2) Å, c = 16.273(2) Å, Z = 4. Compound II: a = 11.662(2) Å, b = 12.948(2) Å, c = 16.285(1) Å, Z = 4. The two polymorphs III-α and III-β crystallize in the monoclinic system. Compound III-α: a = 11.815(2) Å, b = 21.769(3)Å, c = 14.498(4) Å, β = 95.43(2)°, Z = 4, space group P21/c (No. 14). Compound III-β a = 22.154(3) Å, b = 11.550(2)Å, c = 14.230(2) Å, β = 99.05(1)°, Z = 4, space group P21/a (No. 14). All four are Zintl compounds containing novel one-dimensional polymeric chains of 1 [(In2Te6)2-] that can be described as alternating fused five-membered rings [(In3+)2(Te2 2-)(Te2-)], joined at the In atoms.
