Deskripsi
The asymmetric unit of the title compound, (CH6N3)2[Zn2(C6H5O7)2(H2O)2]·2H2O, contains one-half of a centrosymmetric dizinc(II) complex anion, one guanidinium cation and one water molecule. Each ZnII ion is hexacoordinated by two citrate anions, one in a bidentate fashion and the second monodentate, and two water molecules in a distorted octahedral geometry. Intramolecular O—H...O hydrogen bonds add further stability to the molecular structure. In the crystal structure, molecules are linked into a three-dimensional framework by intermolecular N—H...O, O—H...O and C—H...O hydrogen bonds.
