Scientific paper
A satisfactory correlation is described between the bonding energy of a given metal coordinated to a PAH and its observed interstellar depletion. As a consequence, a modelling was elaborated based on the observed depletion of metals and on the theory of thermo-photo-dissociation of organometallic molecules. In this modelling, the abundance of organometallic species is calculated to explain about 5 to 10% of the depletion in the diffuse interstellar medium. Moreover, a constraint on the size distribution of PAHs is presented which is close to the standard distribution deduced by Desert et al. (1990) from a modelling of infrared radiations emitted by the interstellar matter.
