Abstract
In the title compound, [Cu3(C7H3N2O7)2(C7H2N2O7)2(H2O)4]0.54[Cu(C7H3N2O7)2(H2O)2]0.92·4H2O, the CuII ion located on an inversion centre has a fractional site occupancy of 0.54. When this CuII ion is present, a trinuclear complex also involving two adjacent CuII ions arises; when it is not, then the result is two discrete mononuclear complexes. A very similar structure was reported previously by Valigura, Melnık, Koman, Martiŝka, Korabik, Mroziński & Glowiak [Inorg. Chem. Commun. (2004), 7, 548–552]. However, in their material, arising from a different synthesis, the CuII ion with \overline{1} site symmetry is fully occupied, and thus only a trinuclear complex is formed. Here, the mononuclear CuII complex assumes a square-pyramidal coordination geometry, formed by two water molecules and two 3,5-dinitrosalicylate anions, one of which is monodentate and the other bidentate.
