Abstract

Crystal growth of metal tellurides and tellurometalates employing solvothermal reactions at temperatures below 200 degrees C have resulted in four new indium tellurium phases, [Fe(en)(3)](In2Te6) (I), [Zn(en)(3)](In2Te6) (II), and alpha- and beta-[Mo-3(en)(3)(mu(2)-Te-2)(3)(mu(3)-Te)(mu(3)-O)]In2Te6 (III-alpha and III-beta). Single crystal X-ray diffraction analyses show that I and II are isostructural and belong to the orthorhombic crystal system, space group P2(1)2(1)2(1) (No. 19). Compound I: a = 11.654 (1) Angstrom, b = 12.968(2) Angstrom, c = 16.273(2) Angstrom, Z= 4. Compound II: a b = 12.948(2) Angstrom, c = 16.285(1) Angstrom, Z = 4. The two polymorphs III-alpha and III-beta crystallize in the monoclinic system. Compound III-alpha: a = 11.815(2) Angstrom, b = 21.769(3) Angstrom, c = 14.498(4) Angstrom, beta = 95.43(2)degrees, Z = 4, space group P2(1)/c (No. 14). Compound III-beta: a = 22.154(3) Angstrom, b = 11.550(2) Angstrom, c = 14.230(2) Angstrom, beta = 99.05(1)degrees, Z = 4, space group P2(1)/a (No. 14). All four are Zintl compounds containing novel one-dimensional polymeric chains of (1)(infinity)[(In2Te6)(2-)] that can be described as alternating fused five-membered rings [(In3+)(2)(Te2(2-))(Te2-)], joined at the In atoms.
