Quantum chemical calculations were performed on nine dihydrogen-bonded complexes with haloform (F3CH, Cl3CH and Br3CH) as a proton donor and alkali metal hydride (HLi, HNa and HK) as a proton acceptor. MP2/6-311++G(d,p) and B3LYP/6-311++G(d,p) results show that the stabilization energies of these complexes are large and comparable to the stabilization energies of standard H-bonded complexes
Byly provedeny kvantově chemické výpočty na devíti komplexech s neklasickou (-H...H-) vodíkovou vazbou mezi donory (halogen-sustituenty F3CH, Cl3CH a Br3CH) a akceptory protonu (hydridy alkalických kovů HLi, HNa, HK) Výsledky získané MP2/6-311++G(d,p) a B3LYP/6-311++G(d,p) ukazují, že stabilizační energie těchto komplexů jsou velké a jsou srovnatelné se stabilizačními energiemi komplexů se standartní vodíkovou vazbou
