Formation and stability of calcium complexes of dimethyl sulfoxide in water

- Ca2+ interactions with DMSO in water environment using ESI-MS and DFT calculations.
- The number of DMSO ligands in [Ca(DMSO)x]2+ depends on the temperature.
- With increasing capillary temperature the number of DMSO ligands decreases.
- With increasing capillary temperature water molecules substitute the DMSO ligands.
- The bonding energy of DMSO to Ca2+ is strongly influenced by the presence of water.
