摘要
Two hydrazine zinc(ll) telluride polymorphs, (N2H4)(2)ZnTe, have been isolated, using ambient-temperature solution-based techniques, and the crystal structures determined: alpha-(N2H4)(2)ZnTe (1) [P21, a = 7.2157(4) angstrom, b = 11.5439(6) angstrom, c = 7.3909(4) angstrom, beta = 101.296(1)degrees, Z = 4] and beta-(N2H4)(2)ZnTe (2) [Pn, a = 8.1301(5) angstrom, b = 6.9580(5) angstrom, c = 10.7380(7) angstrom, beta = 91.703(l)degrees, Z = 4]. The zinc atoms in 1 and 2 are tetrahedrally bonded to two terminal hydrazine molecules and two bridging tellurium atoms, leading to the formation of extended one-dimensional (1-D) zinc telluride chains, with different chain conformations and packings distinguishing the two polymorphs. Thermal decomposition of (N2H4)2ZnTe first yields crystalline wurtzite (hexagonal) ZnTe at temperatures as low as 200 degrees C, followed by the more stable zinc blende (cubic) form at temperatures above 350 degrees C. The 1-D polymorphs are soluble in hydrazine and can be used as convenient precursors for the low-temperature solution processing of p-type ZnTe semiconducting films.
