Bis(Thiosemicarbazide)Copper(II) 1,5-Naphthalenedisulfonate Complex [Cu(D cent sc)(2)](1,5-Nds): Synthesis and Crystal and Molecular Structures

摘要

The synthesis, analysis, and IR spectroscopic, thermogravimetric, and X-ray diffraction study of [Cu(D cent sc)(2)](Nds) (I), where D cent sc is thiosemicarbazide NH2NHDinverted exclamation(=S)NH2, and 1,5-Nds(2-) is the doubly deprotonated 1,5-naphthalenedisulfoacid anion C10H6(SO3) (2) (2-) , have been performed. Crystal structure units in complex I are [Cu(D cent sc)(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 D cent sc. Crystal structure units in complex I are linked together by a branched network of weak nonlinear N-De center dot center dot center dot D hydrogen bonds with participation of donors (all the five independent hydrogen atoms of the two NH2 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).
