Zusammenfassung: | © 2018 Wiley Periodicals, Inc. Interactions of dimethyl sulfoxide with carbon dioxide and water molecules which induce 18 significantly stable complexes are thoroughly investigated. An addition of CO2 or H2 O molecules into the DMSO⋯1CO2 and DMSO⋯1H2 O systems leads to an increase in the stability of the resulting complexes, in which it is larger for a H2 O addition than a CO2 . The overall stabilization energy of the DMSO⋯1,2CO2 is mainly contributed by the S=O⋯C Lewis acid-base interaction, whereas the O - H⋯O hydrogen bond plays a significant role in stabilizing complexes of DMSO⋯1,2H2 O and DMSO⋯1CO2 ⋯1H2 O. Remarkably, the complexes of DMSO⋯2H2 O are found to be more stable than DMSO⋯1CO2 ⋯1H2 O and DMSO⋯2CO2 . The level of the cooperativity of multiple interactions in ternary complexes tends to decrease in going from DMSO⋯2H2 O to DMSO⋯1CO2 ⋯1H2 O and finally to DMSO⋯2CO2 . It is generally found that the red shift of the O - H bond involved in an O - H⋯O hydrogen bond increases while the blue shift of a C - H bond in a C - H⋯O hydrogen bond decreases when a cooperative effect occurs in ternary complexes as compared to those of the corresponding binary complexes. © 2018 Wiley Periodicals, Inc |
