In the title complex, [Ni(C7H4NO3S)2(C3H10N2)2] or [Ni(sac)2(pen)2] (sac = saccharinate or 1,1,3-trioxo-2,3-dihydro-1λ6,2-benzothiazol-2-ide and pen = propane-1,3-diamine), the NiII ion sits on an inversion center, being coordinated by two N atoms of the sac ligands, which occupy trans positions, and four N atoms of the bidentate pen ligands to define a distorted octahedral geometry. The pen ligands chelate the metal ion, forming a six-membered ring which adopts a half-chair conformation, while the sac ligands adopt the most common coordination mode. The crystal packing is stabilized by N—H
O hydrogen bonds, which form a one-dimensional network along [010]. It is also supported by an N—HS hydrogen bond between the amine group of the pen ligand and the sulfonyl group of the sac ligand.
