A new aqua-soluble CuII-Na coordination polymer, {[Cu(H2O)Na(H2O)(η9-L)]·2H2O}n, was easily generated by self-assembly from copper(II) nitrate, sodium hydroxide and 2-hydroxy-5-nitro-3-(2-(2,4,6-trioxotetrahydropyrimidin- 5(2H)-ylidene)hydrazinyl)benzene sulfonic acid (H3L) a new hydrosoluble arylhydrazone of barbituric acid. The complex was characterized by IR spectroscopy, elemental and singlecrystal X-ray diffraction analyses, which disclosed 1D metal-organic chains driven by the intricate nonachelation of the fully deprotonated L3− derivative to five metal cations (three NaI and two CuII). These chains have intercalated crystallization water molecules enabling the expansion of the structure to 3D by means of extensive hydrogen bond interactions.
