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)](In(2)Te(6)) (I), [Zn(en)(3)](In(2)Te(6)) (II), and alpha- and beta-[Mo(3)(en)(3)(&mgr;(2)-Te(2))(3)(&mgr;(3)-Te)(&mgr;(3)-O)]In(2)Te(6) (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) 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-alpha and III-beta crystallize in the monoclinic system. Compound III-alpha: a = 11.815(2) Å, b = 21.769(3)Å, c = 14.498(4) Å, beta = 95.43(2) degrees, Z = 4, space group P2(1)()/c (No. 14). Compound III-beta: a = 22.154(3) Å, b = 11.550(2)Å, c = 14.230(2) Å, 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 [(In(2)Te(6))(2)(-)] that can be described as alternating fused five-membered rings [(In(3+))(2)(Te(2)(2)(-))(Te(2)(-))], joined at the In atoms.
