Metal cluster organic complexes, neither atomic nor solid but in analogy to atomic nuclei and to mesoscopic systems, have unusual dynamics and catalytic properties. Organo-metal clusters as quintessence prebiotic enzymes could have originated the homochirality of the molecules from achiral precursors, controlled from the atomic-nucleus, with the initial product itself serving subsequently as chiral auxiliary transferring and amplifying the chirality in the autocatalytic process now. High resolution spectroscopic studies of diatomic molecules beginning now may lead to upper estimates of the interaction strength of weak neutral currents (WNG) with valence electrons of metal clusters and suggest kinetic pathways to dynamic symmetry breaking in the asymmetric synthesis of chiral molecules. An estimate of 10-5 kT (thousand times larger than for radiolysis) for the parity violating energy (PVE) could be sufficient to run an entropy driven spin-catalyzed asymmetric synthesis. Expect then, wherever there are metal clusters in interstellar dust or under the sea chiral molecular production.
