摘要：

Positron lifetime parameters were measured for the spin-crossover complexes [Fe(R-1H-tetrazole)(6)](BF(4))(2) (R I-ethyl, 1-n-propyl) and for the diamagnetic [Zn(1-n-propyl-1H-tetrazole)(6)](BF(4))(2). Positronium forms with significant intensity in the studied compounds. The ortho-para conversion of ortho-positronium was used to follow the spin-crossover. Changes of the dynamic structure were found in the propyltetrazole complex between 150 K and 90 K.
