The nitrogen and phosphorus atoms as part of the ions are shown to be divalent with a negative charge and two lone pairs on the nitrogen and phosphorus atoms. The experimentally known calcium sodium iminodisulfonate trihydrate and the analogous unknown compound calcium sodium phosphinodisulfonate trihydrate have also been investigated using the MP2\/6-311+G** calculations. For the nitrogen compound, only minor changes occur in the iminodisulfonate ion when it becomes part of the calcium sodium iminodisulfonate trihydrate. For the phosphorus compound, the geometry of the phosphinodisulfonate ion changes significantly as part of calcium sodium phosphinodisulfonate trihydrate. Furthermore, the charges associated with the atoms in calcium sodium phosphinodisulfonate trihydrate are quite different from those of the phosphinodisulfonate ion. For calcium sodium iminodisulfonate trihydrate, the Raman spectrum has been measured, and it compares well with the spectrum derived using HF\/6-311+G** calculations.<\/jats:p>","DOI":"10.1021\/acsomega.7b00266","type":"journal-article","created":{"date-parts":[[2017,8,11]],"date-time":"2017-08-11T08:17:37Z","timestamp":1502439457000},"page":"4447-4455","source":"Crossref","is-referenced-by-count":0,"title":["Ab Initio Assessment of the Bonding in Disulfonates\nContaining Divalent Nitrogen and Phosphorus Atoms"],"prefix":"10.1021","volume":"2","author":[{"given":"Vinca B.","family":"Andersen","sequence":"first","affiliation":[{"name":"Technical University of Denmark , , DTU building 207 , ,","place":["Kgs.
