Abstract
Two new molecular alloys, the Fe[ (Htrz) (9/4) (NH(2)trz) (3/4) ] . (BF4)(2 ) . H2O(1) and Fe[(Htrz)(3/2) - (NH(2)trz) (1/2) (trz)] ( BF4) . 3H(2)O(2) , are synthesized and investigated by optical measurements (where Htrz stan ds for 4 - H - 1,2,4 - triazole; NH(2)trz for 4 - NH2 - 1,2,4 - triazole). Complexes 1 and 2 show spin transitions with hysteresis and thermochromism in the close vicinity of room temperature.
