We analyze the formation of molecules based on carbon, nitrogen, oxygen and fluorine during the Dark Ages in two different contexts: the standard Big Bang nucleosynthesis model on the one hand and a particular, non-standard nucleosynthesis scenario on the other hand. The latter is particularly efficient in creating heavy nuclei. We also study, in these two different frames, the influence of the molecular H_2 and HD cooling functions on the gas temperature of a collapsing cloud.
