A new complex, [Co(HL)2(H20)4] ·H2O (1) (H2L=5-carboxy-l-carboxymethyl-2-oxidopyridinium), was synthesized and characterized by X-ray single-crystal diffraction, elemental analysis, and IR spectra. The crystal is monoclinic, space group P21/c with a=0.512 69(2) nm, 6=2.275 31(1) nm, c=1.003 95(6) nm,β=98.015(3)°, V= 1.1597(1) nm3, Z=2, Mr=541.29, F(000)=558, DC=1.550 g·cm-3,μ=0.816 mm-1, the final R=0.0445 and WR=0.142 1 for 2015 observed reflections (I2σ(I)). Complex 1 can be considered constructed from 2D layers, which consist of left- and right-handed helical chains and further linked into a 3D supramolecular architecture by hydrogen bonds. Topology analysis reveals that complex 1 shows an unprecedented 3D binodal (5,6)-connected topology.
