Complex [Ni(Tsc)(2)](1.5-Nds) center dot 2H(2)O (I), where Tsc = thiosemicarbazide, NH2NHC(=S)NH2; 1,5-Nds(2-) is double deprotonated anion of 1,5-naphthalene disulfonic acid CH10H6(SO3)(2)(2-) was synthesized, characterized by IR spectroscopy, and studied by thermogravimetry and X-ray diffraction. Crystal I is built of complex cations [Ni(Tsc)(2)](2+), anions (Nds)(2-), and crystallization water molecules. The Ni atom is coordinated along the vertices of the trans-square by two sulfur atoms and two nitrogen atoms of two bidentate chelating ligands Tsc. The structural units of crystal I are joined by a branched network of N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds with the participation of donors, namely, the hydrogen atoms of two NH2 groups and the NH group of complex cation [Cu(Tsc)](2+) and the H atoms of water molecules, and acceptors, namely, oxygen atoms of the sulfate group of anion 1,5-Nds(2-) and solvate water molecules.
