Tetraguanidinium bis[citrato(3−)]cuprate(II) dihydrate
The asymmetric unit of the title compound, (CH6N3)4[Cu(C6H5O7)2]·2H2O, contains one-half of a centrosymmetric CuII complex anion, two guanidinium cations and a water molecule. The CuII ion, lying on a crystallographic inversion center, is hexacoordinated with two citrate anions in a distorted octahedral geometry. An intramolecular O—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, molecules are linked into a three-dimensional framework by intermolecular N—H⋯O and O—H⋯O hydrogen bonds
