Positronium formation in solid transition metal losartanates complexes

- Ps formation in losartan complexes were evaluated by spur and cibotatic.
- I3 parameter was correlated with molar conductivity and periodic properties E0 and χ.
- By cibotatic mechanism, an intermediate is formed by positron and the excited complex.
- Covalence must be an important feature to be considered in positronium formation.
