| Abstract: | In the title compound, Ni(CH5N3S)2(H2O)2](C4H3O4)2·2H2O, the Ni atom lies on a center of symmetry and is coordinated by N and S atoms from two thiosemicarbazide ligands and the O atoms of two water molecules in a distorted octahedral geometry. In the asymmetric unit, the three components are linked together by one O—H?O and two N—H?O hydrogen bonds. The packing is built from molecular ribbons parallel to the b direction, stabilized by intramolecular hydrogen bonds, and by one N—H?S and two N—H?O intermolecular hydrogen bonds. The ribbons are further connected into columns by N—H?O interactions and then into a three‐dimensional network by three O—H?O hydrogen bonds. |
