摘要：
Guanidinium hexabromotellurate(IV), C2H12N6TeBr6, has been synthesized and characterized by element analysis and diffuse reflectance spectroscopy. Its crystal structure has been determined (R=0.027). The complex is built from layers of [TeBr6]2− anions and [CH5N3H]+ cations linked by N–H...Br hydrogen bonds and united by van der Waals interactions into a 3D framework. The electronic factors governing the spectral behavior of the complexes at 100 and 300 K are discussed, and reversible thermochromism has been revealed.
