Abstract: | In the title compound, poly[[triaqua{μ4‐2‐[4,6‐bis(carboxymethylsulfanyl)‐1,3,5‐triazin‐2‐ylsulfanyl]acetato}{μ2‐2‐[4,6‐bis(carboxymethylsulfanyl)‐1,3,5‐triazin‐2‐ylsulfanyl]acetato}barium(II)] monohydrate], {[Ba(C9H8N3O6S3)2(H2O)3]·H2O}n, each BaII atom is nine‐coordinated by six O atoms from carboxylate groups of four different 2‐[4,6‐bis(carboxymethylsulfanyl)‐1,3,5‐triazin‐2‐ylsulfanyl]acetate ligands and three O atoms from water molecules. The triazine ligand is partially deprotonated, as verified by intermolecular hydrogen‐bonding parameters, and adopts μ2‐η1:η1 and μ4‐η1:η1:η2 coordination modes to connect the BaII centres, forming a novel double‐layered structure. Topological analysis indicates that the whole structure is a novel (4,6)‐connected net, considering the ligands and BaII centres as four‐ and six‐connected nodes, respectively. |
