Abstract

Positron lifetime parameters were measured for the spin-crossover complexes [Fe(1-alkyl-1H-tetrazole)6](BF4)2 and [Fe(1,10-phenathroline)2(NCS)2]. If there are structural free volumes large enough (as for [Fe(1-ethyl-1H-tetrazole)6](BF4)2 and Fe(1-propyl-1H-tetrazole)6](BF4)2), there is a significant intensity of positronium (Ps) and the lifetime of o-Ps is a detector of spin-crossover. The intensity of the shortest lifetime component also signals the spin-crossover.
