The structure of the title complex consists of isolated [Cd(C7H4NO3S)2(C4H11NO2)2] units. The Cd2+ cation lies on an inversion centre and is octahedrally coordinated by two N, O -bidentate diethanolamine (dea) and two N-bonded saccharinate (sac) ligands [saccharin is 1,2-benzisothiazol-3(2H)-one 1,1-dioxide]. The dea ligands constitute the equatorial plane of the octahedron, forming two five-membered chelate rings around the CdII ion, while the sac ligands are localized at the axial positions. The Cd-Nsac, Cd-Ndea and Cd-Odea bond distances are 2.3879 (12), 2.3544 (14) and 2.3702 (13) Å, respectively. The H atoms of the free and coordinated hydroxyl groups of the dea ligands are involved in hydrogen bonding with the carbonyl and sulfonyl O atoms of the neighbouring sac ions, while the amine H atom forms a hydrogen bond with the free hydroxyl O atom. The individual molecules are held together by strong hydrogen bonds, forming an infinite three-dimensional network.
