     ...Joining the forces of Tigernoid and Dragonoid endangers the balance of our universe. Even if you had committed no crime, you existence violates the laws of our world.

2. (chemistry) A hypervalent organosilicon compound that features a five-membered coordination heterocycle incorporating a trifluorosilicon moiety (F₃Si–) and an internal Si←O coordination bond.
   • 1993, Voronkov, M.G., Chernov, N.F., Trofimova, O.M. et al., “Organosilicon derivatives of 2-mercapto-substituted benzoxazoles, benzothiazoles and benzimidazoles.”, in Russ Chem Bull, →DOI:

     The reaction of the corresponding alkoxysilanes with boron trifluoride etherate leads to (2-benzoxazolylthiomethyl) and (2-benzothiazolylthiomethyl) substituted trifluorosilanes and methyldifluorosilanes having a dragonoid chelate structure. By the hydrolysis of (2-heterylthiomethyl)trimethoxysilanes, new organosilicon sorbents, poly(2-heteryl-thiomethyl)silsesquioxanes have been synthesized.

   • 2009, Voronkov, M.G., Korlyukov, A.A., Zel’bst, È.A. et al., “Unusual molecular structure of (C=O→Si←O′=C′) bis(2-methyl-4-pyrone-3-oxy)difluoro(λ6)siliconium”, in J Struct Chem, →DOI:

     In developing our research on organic hypervalent silicon compounds containing the F3SimO group included into the five-membered coordination heterocycle, which we called the dragonoids, we decided to obtain a similar organic silicon derivative of 3-hydroxy-2-methyl-4-pyrone (maltol).
