Abstract
The title compound, {[Cu(2,2'-bipy)( C7H4O5S)(H2O)2]·H2O}n?20(2,2'-bipy = 2,2'-bipyridine), was synthesized by the hydrothermal reaction of Cu(NO3)2.3H2O, 2,2'-bipyridine and 2-sulphobenzoic acid, and structurally characterized by single-crystal X-ray diffraction analysis. The crystal is of triclinic, space group P1^- with a = 9.21(3), b = 10.17(3), c = 10.77(3)A, α=77.017(16),β=89.80(8), γ=68.46(7)°, V = 911 (5)A^3, Z=2, (D/S)max =0.001, Mr=473.94, Dc=1.728 g/cm^3,μ(MoKα)=1.365 mm^-1, F(000)=486, the final R=0.0246 and wR = 0.0628 for 3809 observed reflections with I>2σ(I). The mononuclear crystal structure extends into a two-dimensional network via hydrogen-bonding interactions and a three-dimensional framework is further formed by means of π-π stacking interactions.
