Resumo

Complex [Zn(Tsc)2](Nds) · H2O (I) (Tsc is thiosemicarbazide, NH2NHC(=S)NH2, and 1,5-Nds2–is the double-deprotonated anion of 1,5-naphthalenedisulfonic acid, C10H6(SO3)22-) has been synthesized and studied by IR spectroscopy, thermogravimetry, and X-ray diffraction analysis. The structural units of crystal I are complex cations [Zn(Tsc)2]2+, anions (Nds)2–, and crystallization water molecules. The Zn atom is coordinated along the vertices of the distorted tetrahedron by two sulfur atoms and two nitrogen atoms of two bidentate chelate (S,N) Tsc ligands. The structural units of crystal I are joined together by a branched network of the N–H···O hydrogen bonds involving independent donor hydrogen atoms of the NH2 and NH groups of Tsc molecules (nine of ten, except for the H(6A) atom), all six independent acceptor oxygen atoms of the SO3 groups of the Nds2– anions, and two acceptor hydrogen atoms and one donor oxygen atom of the water molecule.
