The synthesis, analysis, and IR spectroscopic, thermogravimetric, and X-ray diffraction study of [Cu(Тsc) 2 ](Nds) ( I ), where Тsc is thiosemicarbazide NH 2 NHС(=S)NH 2 , and 1,5-Nds 2– is the doubly deprotonated 1,5-naphthalenedisulfoacid anion C 10 H 6 (SO 3 ) 2 2– , have been performed. Crystal structure units in complex I are [Cu(Тsc) 2 ] 2+ centrosymmetric complex cations and (Nds) 2– anions (including those in inversion centers). The copper atom is coordinated to the vertices of a square via the two sulfur and two nitrogen atoms of the two bidentate-chelate (S,N) ligands Тsc. Crystal structure units in complex I are linked together by a branched network of weak nonlinear N–Н···О hydrogen bonds with participation of donors (all the five independent hydrogen atoms of the two NH 2 groups and NH group of the [Cu(Tsc)] 2+ complex cation) and acceptors (all the three independent oxygen atoms of the sulfato group of the 1,5-Nds 2– anion).
