The thermal and light‐induced spin transitions in [Fe x Zn 1– x (btzp) 3 ](BF 4 ) 2 and [Fe x Zn 1– x (endi) 3 ](BF 4 ) 2 {btzp = 1,2‐bis(tetrazol‐1‐yl)propane; endi = 1,2‐bis(tetrazol‐1‐yl)ethane} chain compounds have been investigated by magnetic susceptibility, photomagnetism and diffuse reflectivity measurements. These compounds display a thermal spin transition and the Light‐Induced Excited Spin State Trapping (LIESST) effect at low temperature. For each compound, the thermal spin transition temperature, T 1/2 , and the relaxation temperature of the photo‐induced high‐spin state, T (LIESST), have been systematically determined. A decrease in T 1/2 induces an increase in T (LIESST). The results are discussed and compared with some other “metal‐diluted” iron(II) spin crossover (SCO) complexes. (© Wiley‐VCH Verlag GmbH & Co.
