Abstract
A co-crystal of tetrakis(guanidinium) bis(eosinate) hexahydrate (I) was synthesized, and the molecular and crystal structures of (I) were determined by a single-crystal X-ray diffraction technique. The crystal system is triclinic with a space group of P1 and Z = 4. The unit-cell dimensions are a = 14.4774(8)A, b = 14.7735(8)A, c = 15.9316(1)A, with α = 64.739(1)°, β = 70.185(1)°, γ = 70.185(1)°, V = 2871.22(17)A3. The final R value is 0.0462 for 9198 observed reflections (I > 2σ(I)). The crystal packing is predominantly stabilized by hydrogen-bond interactions.
